This is the stuff the factory uses to seal vent covers, seams, tv and radio antenna's.

I did the roof vent cover and now plan on cutting off all the rest of the ols seal on top of my trailer just to apply this since it was so easy to use and effective.

I used this on my toy hauler to put on the roof vent covers and seal them, replaced some lights on my toyhauler and sealed my tub in there.

Works great on sealing or resealing around vent covers on our RV roof.

Great sealant if you are covering up any kind of holes or leaks on the roof of your rv, camper, trailer that has the EPDM style roof

Used this to install new fantastic fans and vent covers, works great.
