Yearly sealing of lights and windows

What type of caulking is recommended for resealing around windows and exterior lights on trailers? Also what is best for sealing around the roof and vents?
Thanks, Curly

Heartland use to use Sikaflex 505UV (available at most RV centers). I like the Sikaflex 221, Bostik 1100, and Chemlink M1. All are polyurethane or polyether based. Stay away from silicone if possible.

For work around the EPDM roof you need a compatible sealant like the Dicor or ProFlex. Chemlink M1 is also approved for use with EPDM

Yearly sealing ??

My '97 5er has never needed the lights or windows to be resealed. Now in all those years I have added a bit of self leveling Dicor in 3-4 spots on the roof.

However I do a twice a year check on all sealed joints on the trailer. Results are it has never leaked.

Thanks very much

3M 4000UV will work wonders around windows and exterior lights and eternabond around the roof and vents. Do this once and probably not for a very long time.
