Body sealant

Okay folks, roof decking and Luan skin complete. Starting the rubber tomorrow... Noticed sealer on many of the body / front and rear caps on my class C.

My front cap is fiberglass, sides are gelcoat/fiberglass/wood ETC. My rear cap is plastic.

What sealer should I use? Looks like what's on there is silicone RTV.

Despite what you've probably heard, Silicone isn't terrible for side seams and windows - it's just the roof where it becomes problematic. Several RV manufacturers use silicone around window frames, for example.

But you can avoid the question by using a product like Geocel Proflex RV or one of the 3M Body Seam Seal variants (often available in auto parts stores). Amazon or Ebay is a good source for either of those as well. The Proflex is available in several colors, but I think the 3M is clear only.
