How to apply 303 on fiberglas roof?

[lanerd]

I have read many times here on this forum and others about using 303 on a fiberglass roof. I know it works well on rubber products.

I looked on Amazon and I can get a gallon of this stuff for about $42 bucks. My question is how do you apply it to the roof, how much will it take (I have a 44' mh) and how often do you apply it?

Thanks,

Ron

I do my roof twice a year with protect all. I just go to the dollar store get one of the sponge mops for a buck. Go up on the roof spay the product on the roof wipe it on with the mop and I'm done no more crawling around on my knees.

Is your trailer fiberglass?

I do my whole trailer with a few oz.
Just mist it on and wipe off, it's not like buffing with wax.
