Details for Clear Coat Repair

I have areas where the clear coat is coming off. I got a quote for $3K to repair and it is more than I want to spend right now. I would like to try and repair a small area and see how it goes. I have read that others have done this with varying degrees of success.

Questions:

What is the "best" clear coat to get? Should I get a spray or brush on? What exact brand/type do I get?

When you are using sand paper, I assume you go around the edges until you have gotten into a solid area. What type of sand paper? How do you do this so you do not sand off the paint?

How do you clean the area before you put on the clear coat?

Anything else I should know before attempting this?

Everybody has different standards, budget and skills for a repaint project.

I have tried to blend new clear coat over gel coat. This only lasts a couple of years.

I have applied base coat with new clear coat. This lasts longer.

Q1 You will want to spray clear coat. Depending on the Orange Peel in your result you may need to Sand with 1200 grit and higher wet sandpaper and the buff the result with polish.

Lots of people use the 2 part SprayMax 2K for small repairs to cars, and motorcycles, guitars, and other shiny objects. Buy it at your Automotive Paint Supply Store.

Q2 Sanding the good clear coat will allow the new Clear Coat to adhere to the old Clear Coat and maybe the base coat. But, if you sand the exposed base coat, the resulting color may be different from the surrounding good areas. So really one needs to spray new base (color) coat and then spray the clear coat.

Also, if trying to blend the repair into the remaining good clear coated surface you likely will get ridges where the layers meet that may need to be sanded out if possible. Up on the roof cap this would be a small problem. At eye level it will be very apparent.

Q3 Buy a cleaner from your Auto Paint Supply store when you also buy your SprayMax 2K Clear Coat. They can also try to match your base coat color and put it in a Spray Can.

There is a lot of help on the Internet for this process. Do some surfing before painting.

But.......if you want a long lasting, looking like new paint repair, have a pro do the work.

It is tough to find the right weather day for outdoor painting, then mask the area for painting, only to have the wind come up and the bugs come out to affect the quality and appearance of your spray job. Been there, done that.

PS....I bought a $150 scaffold from Harbor Freight (Home Depot has them also) that makes working high up much easier than standing on a ladder. It also makes a nice garage storage shelf when not in use.

Well, we did and do our own. Looks good to me. Re the above the drip rail area. Sand with 400 to 600 grit. Don't worry about going through the base coat. Its just paint. Once its smooth use a product like final wipe. Mask at least 4 feet in every direction. Once more with final wipe. 2 coats of base coat and then 4 coats with Spraymax2K. Make sure you get the base coat and the Spraymax2K from the same place so they are compatible. All the coats 10 to 15 minutes apart. First coat of Spraymax2K lighter and the rest a little heavier. If you go to heavy and make a run don't touch it. It'll look all right in the end. Spraymax2K is a true two part clear coat. You puncture the internal cylinder in the can and then the two mix. You have about 36 hours to use the clear coat at that point.

Is it perfect? Nope. But it looks excellent to me. The first areas I did were about 5 years ago and I may have to redo those in the next year or two because I tried to blend and not redo the basecoat. The parts that I took it right down look great and are hanging in there. We need to make the coach last another 15 years or so. Meh, should make it 🙂

Cost is under a hundred bucks for a 40 foot coach both sides (assuming we are talking about the area above the drip rail) I used a ryobi cordless sander. I buffed it out with a power buffer but that is another topic that Ill cover if you decide to go that way.

I seem to have to do a little on the coach (black and dark brown part of the sidewalls) every year or two (we have had our coach since new for 11 years now) I seem to get a little better every year. Kinda fun, relaxing, I do it all outside in the fresh air. I use a mask when spraying. The paint part is the only fast part. All 6 coats are done in one hour.

By the way, this also works on the fracturing on the side walls but the fracturing will show up again within three years.

Good luck.

Sorry I don't have a better picture.

Oh and the reason(s) I do it myself are

a. money (3000 5000) bucks is a fair chunk of change for us not to mention that pretty much pays for 2 months exploring europe for us.

b. If I hire someone it is just another missed opportunity to learn something. My dad wouldn't have approved. 🙂 Besides Angela does most of the hard stuff. 🙂

Tell us all about your previous painting experience and some of us may change our mind about our recommendation to have a professional do it.

I mean no offense, but in my experience, if a person has the skill and tools to do a specialty job, he does not bother to ask other peoples opinion. He just does it.

Thanks for all the info. I would like to get other quotes to see if I really need to pay this much. I am about a 2-1/2 hour drive from Las Vegas. Does anyone know a reputable paint shop there?

Just one suggestion; I would seek out a "bumper repair" specialist. Check with local car dealers for a source. They will come to your place and do the repair. I've used two in the past on Mercedes bumpers, and the work is top notch.

It is interesting that not one person has ask the OP to get additional quotes. How do we know if it reasonbale or not. Is it 2 square feet or 800 square feet? Being the roofline it is not like people or going to be 18 inches away from the repair. Granted the poster ask for opinions, but why does everyone have to assume this person even has the $3,000. to begin with?

If you do not care how it looks go to Wally World and get
a can of clear spray paint.

Modern paint is way different from the oil based paints of
the 30s-40s or 50s or even the enamels of 60s-70s.

I sprayed my front cap with a nice gravity feed sprayer and it looked okay for two years. I waxed it regularly and I thought I dodged a bullit, but clear coat deterioration is like cancer. It will continue to grow and go bad, mostly along the roof line, and will eventually have to be sanded down, repainted and shot with new clear coat.

Well, for all the nay sayers there must be a reason they sell millions of cans of car color matched paint. As suggested, it won't cost much to do it yourself. Heck, I painted a 54 Willies Jeep with a can of rustoleum and it looked great. Not show room but no runs. There are thousands of inexperienced do it yourselfers out here that can indeed learn to rattle can a good looking minor repair. This is a cosmetic repair along the top cap where the dark paint gets over 160 degrees. I doubt anything will hold up under those intense temps. My MH will burn your hand on the dark paint when sitting in the direct sun. I have used a heat gun and it will stun you how hot it can get.,

Clear coat has to be comparable with the paint system used.
Example if it is lacquer it has t be lacquer.
If it is a Polyurethane his has to be polyurethane.
Most today are a polyurethane.

The lifting is usually caused by improper bonding in the
paint process. This can happen for many reasons.

In the "old days" the clear coat was on top for protection.
Today it is a part of the paint system. The color coats have
no gloss until re-coated with the clear. You need good spray
equipment and experience in preparing the surface for re coating.
The surface prep will determine both how it looks and how long
the resurfacing lasts.

This is not a casual DIY job.

It is pretty easy to get the repair to look good and last for a few years, but the problem may stem from a deeper problem. If the clear coat is put over gel coat, or fiberglass, It will not stay for very long due to exposure to the environment, mainly the sun. Sometimes the paint is applied too thick and will fail. if the substrate is not prepared correctly, primer, sealer, etc, it will fail. Other things that causes failure on MHs is the color difference/design. As mention earlier, some colors heat-up more that others and cause stress in the surrounding areas. Giving advice on how to repair clear coat on this forum is next to impossible. Look at car/truck paint, and how some fail, and others do not. If you have any experience painting, give it a try, you will not be out that much money and it will probably look better than it does now. If not, it will give you some appreciation for having a pro do it.

I suggest those that have done this repair themselves post some pics of the results so the OP can see the results and whether or not he could live with them.

Just to add a little gas to the fire -- if you are going to pay you need to find someone who is REALLY GOOD -- you, like many of us, have a professional job, that has turned to crap! So what I'm hearing here is to pay to have it done right, but.......just don't pay the same guy again who did it wrong.
