Anyone interested in 83 Pace Arrow Tear down and Rebuild?

Thanks for the reply regarding the adhesive use. I think I am going to give the Chemlink a shot. I used a few different kinds of construction adhesive to varying degrees of success and I think having something that will remain somewhat pliable would be a good thing.

One thing that seemed to be a pervasive situation for me was not being able to spread the adhesives quickly enough; I'm in Florida, so I attributed some of that to humidity on the moisture cure adhesives. That's where the water based contact adhesive was good as it took almost too long to tack.

Looking forward to seeing how your roof gluing goes. I remember the day I finally coated my aluminum roof. I spent countless hours prepping the aluminum, removing old coatings, some of which clearly weren't properly applied. Once I had all the old coatings removed and everything cleaned and ready for the two-part liquid EPDM roofing, and I had a good weather window, I barely slept the night before. I was both excited and nervous as I'd never used the product before. I was so relieved once I finished. It came out well and best of all, it stayed dry inside.

Like you, I looked at all the leaks from the perspective of wanting to go back together in a manner that wouldn't encourage similar issues down the road. I do still have the roof penetrations, but I sealed all the layers so that if a vent or A/C gasket did fail, it would be unable to get inside the roof system and would have to just fall to the floor where it would quickly be noticed. I did the same to all the windows as well, now if there is a sealant or gasket failure, water won't make its way into the layers, it will have to run inside where it will be much more easily noticed. Once you have torn into a RV wall that's been water damaged it certainly gives you a perspective on how to prevent future leaks, and a sincere motivation to keep the water out of your hard work!

Are you sure that roofing is TPO? I always was told the way to tell if your roof was EPDM would be White on the top and Black on the bottom and TPO would be White on Both sides.

Here's a silly question. Anyone ever try using TPO on the outside walls of a motorhome?

Actually, when I first saw you testing the TPO material the thought crossed my mind wondering how it would work as the exterior siding. You can obviously get it wide enough to cover from roof to bottom with one sheet (which you can't do with filon) and it is definitely durable. I wonder how it would take a paint finish?

I had to re-laminate a good amount of the filon on the exterior of my rig, and I can tell you the stuff is brittle! The TPO certainly seems like it doesn't suffer the same in that department. It would definitely be interesting to see how it fared as a motor home siding.

And there we go! It's up there! Wahoo!

Fits just like a glove! After finishing the installation of the grommet, it's just not going anywhere.

The fiberglass in the TPO will not allow that grommet to go anywhere.

It's a lot easier to pull them out of a tarp, as I never was able to pull one of these out of the TPO.

In order to keep the TPO from blowing away during the next few days of rain that is supposed to be coming, I needed a way to hold it in place after putting it on the roof.

I wanted to add some grommets along the sides to hook my straps to. Wouldn't you know it? The best way I found to cut the hole for the grommet, was to "drill it"! That TPO/rubber in .060, is tough stuff.

After drilling, the hole is just a touch jagged, but still able to get the grommet in place.

The PT rides again! This is what I did, when I needed to move the left over piece of rubber, and needed some assistance getting it back inside the car.

Yea, hooked up a ratchet strap, and applied some pressure, and gave it a little extra help with my hands. Little slow, but after a few of these, I was able to get it inside.

By the way, I did make sure the place I hooked would stand the pressure. It's the hook to hold the rear hatch closed, and it's pretty sturdy.

It was during this time, that I broke my nail, (like anyone cares, Lol).

Here's what part of my day looked like. I rolled out some TPO to get ready to cut off a piece 25' long.







Flipped it over, after cutting, to make sure I didn't get a huge bunch of grass on the back side.

AHHHHHHHHHH! What a horrible day! I think I may need to take the rest of the week off. I injured myself today. Look what I did!






I BROKE A FINGER NAIL! AHHH! LOL!

Calm down, I trimmed and filed it back into a non catching nail. You know, when you brush against your shirt, or pants, and it catches on them? Yea, it's not doing that any more. Disaster averted.
