Jeremy and forum guests,
I painted a larger piece of scrap plywood with black Repti-Shield, because I like to waste money apparently in my quest for knowledge.
Repti-Shield is kind of thick, the black reminds one of molasses. Stirring it helps with the consistency.
What I found was the product starts to cure quickly on the wood as I painted from left to right. By the time I got to the end of the larger piece, going back to the starting point was difficult due to the coating getting very sticky by then. If you have ever fiberglassed a surfboard, it is like that. Work quickly and move from one end to the other.
Just to test, I put some more on a few spots after those areas started gelling up. No big deal, it still worked, just really hard to paint due to the stickiness.
One coat on pine plywood may be pretty good for protection but shows all of the wood grain, just like polyurethane does. Two coats gave a more glossy lustre and a bit more smooth of a surface. Divots in the plywood filled in nicely. I imagine this product will flow into seams and make for a good seal.
I want to give the piece of wood I painted another few days before I start washing it, flexing it, etc to see how it holds up. Like I said before, this coating is much tougher than polyurethane but thinner than a coat of polyester resin or pour epoxy. Very shiny so it shows the texture and imperfections in the wood just like gloss paint does.
I dropped some on my garage floor. It works well on cement I found out! Ooh, a black garage floor. I wonder if it can coat foam fake rock?
