Gordon, Looks like you are the guru of sealants so a couple of questions.
Seeing as I just re-applied the sealants/caulk on the bedroom slide last week and then I read the posts here that say don't use sillycone on an RV, (my luck, day late and dollar short).
1. Do I need to dig it off and replace it or wait until it goes bad again?
2. Any special cleanup instructions before applying, cleaning with alcohol or other product? Would be wasting good whiskey!
3. Any suggestions to keep the darn stuff from turning brown/black as in dirty twice as fast as the rest of outside?
Thank's for any advice here, that one bugs the heck out of me and drive's me to the above mentioned product!
