How many gallons for 1 coat on 43ft 5th wheel roof? Thanks

Our 100% Silicone Roof Patch product is used to reseal the roof seams and penetrations. For the rest of the roof, we suggest using or 100% Silicone Roof Sealant. That product can be applied with a 3/8 nap roller. For a 43ft, you will need right around 7 gallons for proper coverage doing one thick coat.

Will this product adhere to existing silicone?

I put it over existing silicone on the corner of my trailer, it worked very well. Just make sure that you clean the roof area very well, I used lacquer thinner to give it a good substrate to adhere to.
