Before I choose a kit, I always look at a few important things:
- Surface compatibility: I make sure the kit is made specifically for fiberglass or FRP surfaces.

How I Compare Price and Value
I don’t just look at the lowest price. I compare what each kit includes and how long the finish is expected to last.
