Exterior Seam Caulking
We are in the process of doing end of season maintenance and have found several sidewall/trim areas that need to be resealed. 1 year seal check was done by dealer. What Caulk do you find to be the best for non-roof related repairs. Our previous unit (Jayco) we were told to only use Lexal. Current appears to be regular silicone which I know needs to be removed before re-applying. Opinions on which is better, Geocel ProFlex RV, 3m RV/Marine or Lexal? I called Montana customer service and they were no help.

Pro Flex RV, clear for walls.
Alpha Systems self leveling sealant or Dicor self leveling sealant for the roof.

I use clear silicon for metal-to-metal or metal-to-plastic. Self-leveling Dicor on the flat portion of the roof and non-self-leveling Dicor on the edges of the roof.
I try not to go over the top of old silicon; remove if possible. I do not try to remove old Dicor.
