Very off topic project I am doing but I am trying to replicate some over quarter fenders for the rear of my 94 rx7, I recently bought the rear over quarters a month ago and they just showed up, anyways these panels are 1100 shipped from japan and I need two sets and I only have one so I have to make a mold to make another set as I have two cars that need them. My question is what materials to use, how to flange this part for a mold, and can I use evercoat pva or do i need wax to release mold from part?

So the part is 4mm thick, so its very thin, should I add in strips of wood and hot glue them in?

4mm thick is pretty thick for composites! Legal requirement for fibreglass replacement panels is 3mm, so 4mm is absolutely fine. They must be pretty heavy for what they are! 

OK, i did order pva and i am picking up some relase wax pretty soon, what material oz would u use?

What do you want to make them out of? Carbon fibre, fibreglass, Kevlar? Do you have vacuum equipment or will you be wet-laying these?

Hi the parts I am making are going to be fiberglass and I do not have a vacumme source 

Ok. In that case I would go for 3 layers of 225g and 2 layers of 450g chopped strand. You could use 5 layers of a 260g woven glass too, but woven fabrics are a bit harder to wet-lay without vacuum. 

I'll be doing the same for my JZZ30 when i get skilled enough with vacuum infusion so im gonna have to follow this and see how you get on dude
