I’m putting this up to show begginers and maybe some not so begginers how a hood and trunk mold is made. I’m sure there are many different ways to plug up a hood or trunk, this just shows how I chose to do it.
I used thin aluminum sheetmetal .010" gauge. I believe it is clad coated. Resin won’t stick to it… part of the reason i love working with it 
Also i can cut it easily with tin shears. I used modeling clay to fill in all the gaps. Tiny drill holes in the trunk i used blue masking tape and exacto’d it to shape. I waxed the trunk 10 times with TR104 mold release. As much as i do not like using PVA i laid down a coating of it to help with release… this is a somewhat expensive mold so i didn’t want it sticking to the plug.
I used 1.2 quarts of polyester tooling gel coat… that gave me a 12 mil thickness. I should have done more but my neighbors were complaining about the fumes. Gel coat really stinks and will get you high within a few minutes. I always wear a respirator.
The hood is in the begging stages of plug making. It was a very plain looking hood in oem form. the customer wants heat extractor vents and possibly ram air. I’m still thinking about the ram air part… got most of it figured out but the inlets.
Remember this is in very rough form as I am just starting…
