This week I'll be recaulking some of the outside of our 5er. Which type of caulk is the best to use?

He also recommended mineral spirits to clean the spot off, thoroughly drying before apply new caulk. After caulking, apply some mineral spirits to get the professional look by using a slightly round plastic scraping tool for edges.

It works very well.

I used the clear. It was horrible peeled off like Silicone. Read up on it. Its the only product available for use in California. I found the problem. Went back to black and white California non complient sealant.

Not sure how you prepped, but my Northwood 5th wheel had clear 2300 MHRV from the factory on front cap sides and underneath. I just had to remove all the caulk to get it painted. It never flaked. I wished it had. 😞 5er's 5 years old with the original 2300 on it. I re-applied 2300 since it held up that long. Bought too much so I decided to do the exterior this week.

Sorry. I used the Geocell Proflex in clear...not the Geocell 2300.

Thanks for that info. I'll try a tube of that the next time I need to caulk my camper.

That Geocel Pro Flex is really hard to find. I live in the Minneapolis/St. Paul area and I had to order it online; no store had it in stock that I could find. Thanks for your help.

I used home depot- Rapid Set non-sag hybrid silane polyether easy flow in white.. it was cheap, worked great, and was easy to use ...

That video was called... (mrrvtech.com... how to properly silicone your rv *4min13sec)
It shows the dawn dishwashing liquid trick and by using that method mine came out looking like a professional did it...

[RvNewbieFl]

I resealed the entire rv and re sealed the roof...I will say... on the visible seems... if you use the dawn dishwashing liquid trick ...it actually works and makes it look like a professional resealed it...

If you go with Geocell Proflex which in my experience is the best, you better have strong hands or an electric caulking gun. That stuff is very difficult to get out of the tube unless you have a large part of the tip cut off. Cutting off just a small portion of the tip trying to get a narrow bead is an exercise in futility. I did that with the first tube I bought and I squeezed so hard trying to get the caulk to come out that I bent the caulking gun handle (for those of you wondering..did he puncture the foil on the tube..Yes I did. Not my first rodeo)Also, plan on throwing away what you don't use. It's expensive but unless you plan on continuing the next day, forget it. That stuff left in the tip cures and makes the rest of the caulk useless unless you want to slice open the tube and glob it on somewhere. Then it would work fine.

Removing all the old caulk first and using masking tape on the outside of the bead of caulk will assure you of a nice looking job

Geocell Proflex for everything but the roof. You got to remove old silicone 1st

If you're going to be on your roof, it will be a good time to apply Eternabond to the seams and edges.
Just a thought.

Dicor has two formulas. One for roofs and another for vertical surfaces. Others like Proflex. I was never able to get it to stick.
