Caulk for A-Frame Chalet Pop-up
I have a 2009 Chalet Arrowhead A frame popup camper and I was wondering what is the best caulk to use around the seams on the top and around the bubble windows? (See pic #1) It's a hard sided fiberglass construction. I started to use 100% silicone and then read that silicone shouldn't be used? If so why?
Also the pivot area where the sides go up will need to be re-caulked and there must be some special caulk that is really flexible to go there (see pic #2) Any suggestions would be greatly appreciated.
