....I removed and replaced every sheet metal screw on our camper (an aluminum-framed camper), replacing every screw with high-quality stainless-steel screws (this includes every screw in the roof: all roof hatches and rear ladder screws), thread and hole-bedding every one of them with 3M's 4200. I use 4200 as a bedding compound, not a seam caulk. The only thing I use for seam caulking (fiberglass to J-trim metal) is Geocel (Geocel, the formula I use) is the stuff you probably refer to as: firm, high-gloss and dirt-repellent. If you make mistakes with Geocel, it is a real b**$h to remove. Be very, very careful.
BTW: 4200 will attract grime like crazy in my experience. I go with a firm seam caulk (like Geocel) for all the big seam work.
I planned on the stainless screws also because strangely only the lower screws were rusted.
The water must be following behind the trim cover from the overhead around to the bottom and passing thru the screw holes.
Thanks for the feedback on the 3M 4200. Will be testing the Geocel soon, hope it is the right stuff.
Strange the airstream people never mention Geocel.
