Right now I am making a fiberglass door piece for my speakers and cossovers and I am wanting to paint them but i am not sure exactly how thick paint really is...im trying to find out so i can make the correct gap for my crossover display.

I have the speaker piece made and my crossover display piece made but, im wondering if I have to make the "gap" from the edge of the crossover to the edge of the fiberglass piece bigger.

Here is what it looks like:

In this piece, the fiberglass is right against the crossover but if i back down the crossover to where it needs to be, there will be a gap. When I made this, i used 1 layer of masking tape to create a gap, as well as to protect the piece from the fiberglass resin

(when i was making it)


(after its sanded)



Can anyone tell me if 1 band of masking tape is the correct thickness that I need? Or do I need to make a new one with a few more layers to make the space needed for when its pained, the crossover will fit as perfect as possible?

Thanks for your time!
