sealing seams
Many of the vertical seams on the exterior of my Class C have accumulated black "gunk" from years on the road. In a few locations it looks like there's some gaps which need to be filled.
My plan is to remove the existing caulk, using a plastic scraper, clean out the residue with mineral spirits, and apply new caulk/sealant.
Two questions:
1. What sealant is appropriate for this use? I'm also replacing some exterior marker lighting fixtures... can the same sealant be used for this? I'm thinking that some ordinary white silicone caulk would do, but perhaps there's something else I should use for this application?
2. Should the caulk be applied with a "bead" so that it's raised up a bit over the surfaces, or should it be smoothed into place with a finger as it's applies?
Anything else I should be thinking about?
