I'll be skinning my teardrop soon, and I have a question.
The main reason I am doing PMF is because I like the notion of a continuous waterproof skin on the teardrop: I like it so much that I'm even going to skin the kitchen, the shelves and all that. I am intentionally overbuilding this thing, in terms of watertightness, because I don't want to have to deal with a leak down the road. I also like how it looks, and the ability to paint it any color I want, but utility is the main reason I'm going that route.
But I am wondering about screws going through the canvas and the camper frame behind it: I'm going to keep these to an absolute minimum, but I can't avoid attaching at least a few things to the outside of the camper: I need brake lights, and I'm going to need to fasten a license plate holder to the back. And I'm toying around with the idea of putting cross bars on top of the camper, and even a fishing rod rack in the front -- I may or may not do these, but if I do, I want to put them in now, rather than trying to retrofit them later.
What did those of you who have used a PMF skin do to seal screw holes? Do you do what boat guys do on fiberglass, which is to use 3M 5200 around the screws/bolts? Or did you do something else? And how have those results held up?
