I don't know the answer to that, but in most builds I have seen they either Bondo over or wood filler over the screws. I always assumed it was a possible weak spot so you would want it as reinforced as possible. I could imagine under all that pressure water some how finding a way past the epoxy could use the screw threads to make an escape.....but if it gets through the epoxy aren't you kind of boned anyway?
Same reason i didnt understand why people use stainless screws and marine grade plywood. I did use stainless screws for the plywood just to keep moving forward though wasnt worth gettin into it

I mix my resin very slowly for about 5 minutes dealin with about 200ml at a time. I find it near impossible to pour it without getting these microbubbles. I spread it around with a putty knife for the floor but the walls ill be using a roller which ive noticed makes more bubbles. Should i be using a heat gun to try to get these bubbles out while its wet?IMG_20200314_103047.jpg

From what I've read an aluminum roller should get these bubbles out. Is that what you are using?

Today i noticed the fiberglass actually has alot of raised spots with air pockets underneath it from not being able to flatten the cloth down 100%. Its minor but I think ill sand these spots down once it cures then add another coat of epoxyIMG_20200314_141857.jpg
