Pro Flex For Roofs Vs RV Pro Flex?

[BreakAes]

Hi all,

I'm leaning towards using Pro Flex for the sides of my truck camper: a 1996 Lance Squire 8000 with aluminum sides and roof.

I read an article which said that the Pro Flex for roofing is better and more inexpensive than the Pro Flex for RVs. I'm going to call Geocel and ask about this, but does anybody have information on if that's true?

I know that some people hate working with Pro Flex. One of the advantages to Pro Flex is that it can be applied over itself, whereas I understand that silicone can't.

The Amazon page for Pro Flex said it's supposed to last 25 years. I don't know if that's accurate, but it would be nice if it were true.

Any thoughts as to approximately how long Pro Flex will last? Right now my truck camper is stored under cover.

Seems there are pros and cons to each sealant choice, but I'm leaning towards Pro Flex for the sides because it seems the best overall from what I've read so far.

For the camper's roof, I'm still doing research, and I'll post another topic about that.

Probably most of the the well-known brands of roof lap sealant or caulk will last 25 years, but that's in a laboratory weathering test. In practice, RV joints stretch & twist, and heat & cool, so the joint may or may not last that long.


Geocel make their Roof Pro product and also the 2300/2350 and 4300 caulks that would probably work well for you. Sika also has a wide variety of excellent sealant products (Sikaflex and others).
