You're in FL. So good for you.
The Home Depot sells the product you need only in FL.
I used it.
I had a guy come out and do it to replace all the stuff on top and coat it.
Its Lanco brand.
Buy the premium.
Goes on Blue and dries White.
Spent months exposed.
Then dry storage for last 1.5 years.
I rinsed off and recoated it a couple weeks ago and brought it to FL April 15.
Roof looks brand new.
If you need a pro, I still have the RV Repair guys info.
