I do favor use of KoolSeal on the roof, but not on the curve where it can be seen. Paint is the normal application for a GMC but KS will reflect the suns rays and heat where paint can't do that. That is what I think a GMCer would need it for. The surface inside the coach that has the KoolSeal above it will be cool to touch, even in the hot sun. ( I do not sell this product, I have used it and know what it can do. )
I just looked at the kool seal site, they have increased their product line since I used it.
I am going to guess that you just want a top coating to reflect the heat, it will also protect and weatherize the roof.
That would be the
RV Rubber Roof TopCoat White Elastomeric
#63-900
The benefits of Kool Seal elastomerics for your RV or mobile home! Reflects up to 90% of the sun's rays to keep you cooler and save on energy costs.
Reflects 90% of the sun's rays
Keeps interior cooler and saves energy
Gives added protection, extends life of roof
Makes repairs blend in to look like new
Easy to apply with deep nap roller or brush
Dried film is mildew and algae resistant
Soap and water cleanup - while wet
I will mention before you get going, the KoolSeal does require minimum maintenance, once a year or two, you may have to clean it with a soft soap to clean any dirt off of it. The cleaner it is, the more it reflects. My roof lasted way over 10 years after application.
Do you have any seam issues??? Leaks??
They sell a cloth that you would saturate with KS over the seam, or around the brackets that hold the railing. you would make 2 or 3 applications, letting each application cure for a few hours. You saturate the cloth each time and by the time you are done, the cloth looks like a patch of rubber, it will expand and contract with any movement of the seam and seals the seam from water penetration.
They have some other items for leaks that are new products, I have not used them so I cannot vouch for them.
KS is an interesting product and I have had good luck with it on 2 sob's. I tried to just paint the GMC with Brite white paint but it still heats up so I am thinking in the KS direction.
Would be happy to chat if any questions...
