Why not use what is designed for use on Rvs. I hope you are good at it as it make a rig look like the dickens if not done right. Dicor has the right stuff ! JMHO Jb

J, I have run Miles of pure silicone (part of my job) while silicone takes a little more skill to handle (no do overs) I would put it up against any other sealent for long term adhesion and flexibility. I have also had many Non White Rigs, Silicone offers easily available colors for matching. On many RV,s 1/8" beads need to be run along surfaces that are 16" ths on different planes, with Blue Painters tape running above and below the strike point even an amateur can get tight clean lines.... Silicone will stick well to most RV surfaces provided the proper prep, cleaning, etc...

Sidewalls use ProFlex RV (clear or white). For roof penetrations (AC, fridge vent, skylights) use Dicor. Best chemical for prep is Klean-Strip Industrial Maintenance Coating Thinner which is sold by Home Depot.

Try mineral spirits first, it may be all you need. Just dampen a cloth with it, never pour it on. Use the sealants mentioned above, never silicone. If you wet your finger with mineral spirits you can really smooth your sealant bead.

I won't use silicone on my rig - too many threads indicating problems and nothing likes to stick to it. I tend to stick to dicor, eternabond and pro flex.
