Rusty Screw

[Masch]

So I decided to clean the 3 slides to put protect all roof treatment on. I washed the roof and sides. No big deal, except one screw on the curb side slide kept dripping water. It looked to be backed out a few threads. I removed the screw and found it be be rusted, has had water before. So what do you guys think? Water went in around the screw cause it was loose, or water entered from the slide roof. This screw holds the trim. I can put silicone around the screw and replace it. Silicon between the roof and trim, or lap seal between the roof and trim? I seem to remember someone saying silicone would not stick to the slide out roof?

I would replace the existing screw using a sealant. Check both the side and the top for any water damage. If no water damage, I would then reseal the top of the angled trim. I’m betting that’s the source of the water.

Hope this helps

Thanks Don, I will take your advice, would you use a silicon caulk or lap seal for the top, just seems someone one once talked about silicon caulking not sticking to the rubber roof stuff.

Not suggested to use silicone on rubber roof, Dicor makes a non sag Ive used it on other trim to and sticks great.

Thanks guys, I will order Dicor this weekend.

Mike, sorry for the late reply. The Dicor described is a good choice. Also a product called Proflex that some folks swear by is available at most RV parts stores. It tends to be a bit more fussy to apply as it is "sticky and thick" and doesn't lay and smooth easily (in my opinion). Just FYI.

Thanks again, I don't understand why PI did not seal this area. I can only ASSUME, the rubber wraps underneath the angle iron trim, but the screws would still put a hole through it. Over thinking stuff, I think I will go ahead and put the Dicor on all the slide trims
