A friend who was restoring an old airstream gave me some parbond to try out on my Alaskan camper. I find it much easier to apply than other sealants I’ve tried.

Some great info here!  FWIW, my Ovrlnd Camper popup builder uses and recommended to me 3M 540 sealant/adhesive.  Works great other than the limited open life others have mentioned. supposed to be very UV resistant— we’ll see how it goes in Phoenix …

 

i called 3M on recommendations for VHB that could stand very high temps. Finally got to a VHB technical specialist who recommended 5952. very high temp tolerance — 300°!  Also very wide range of surface energy adherance. Seems to stick incredibly well on every thing, especially with Primer 94 adhesion promoter. The key is to clamp/roll it well and let it set for 24hrs.

For stuff like non-potable water and other pipe fittings I use Lock-tite 545, but in some cases I use Hylomar. Hylomar is a non-hardening polyurethane blue goo that will NOT easily come out of clothing. You were warned! My local CarQuest stocks it, but not all of them do. Never seen it at any of the "big box" auto parts stores.

 

For an exterior sealant I un-apologetically go straight to 3M 5200 in most cases. Not a fan of any type of silicone sealant except for the "Right Stuff", but that is more for mechanicals like engines and axles than camper stuff.

I recently started researching VHB tape as a possible method of attaching our new solar panels to our roof. I found that the manufacturer, 3M, has a wealth of information on their website. I was even able to reach out to one of their technical staff who got back to me the next day. There really is a lot of science behind the product.
