I thought silicon caulk on a camper/trailer was a big no no?
Most campers (all?) have the trim caulked with silicone to start with. I am slowly getting to all the exterior trim and replacing the silicone on ours.
This is exactly what I noticed when looking at new trailers. I was really surprised. Guess I should not have been. I will start to replace the silicone with something else too. Just not sure what yet. I was using 3M 4200 marine caulk and it worked great. I think it only comes in white and the new trailer is not white so might look funny. Need to check if it comes in clear.
Comes white or black. Most of the trim is black so that should work.
Silicone being a no no is a common RV board misconception. Keystone RV uses silicone for every joint that is not against roof membrane but its not the silicone you run out and buy at the big box. They were using Tremco Trempro, at least as late as 2013, a neutral cure high quality silicone caulk that is really tenacious when it comes to adhesion.
Most Forest River brands almost all use Geocell Proflex.
Where people get into trouble is attempting to touch up non silicone caulk with silicone or vice versa. Sometimes when touching up silicone with silicone. They key to touching up silicone is to use the exact same product, clean it properly, and use a primer.
