303 on roof

I've heard of using 303 on fiberglass gel coated mh roofs to prevent oxidation and white streaks. My question is: is one coat enough, or should I put more, and if yes, how many more?

thanks,

Ron

    This stuff works great...
  • We use a mixture of 303 and mop and glow here in Florida. So far it seems to work pretty good. I leave the RV out on the sun 365 in central Florida. I only need to apply the mix once a year, or maybe a little longer. I look at the roof once a month when we take her out camping.
  • I think I will go for two. Gotta be better than one.

    Tnx

  • I'd go for two if you want much longer protection. It is good stuff, you will like it.
  • One coat of 303 is sufficient but two will last longer.
  • I use Protectall and put it on with a sponge mop from the dollar store. I just spray and spread it on and don't worry about wiping it off. And can do it all standing up.
