Little update for you.
Going to make a carbon fiber Hood and GT Porsche Seats from my steel originals.
Needed to media-blast, seal, fill, prime and topcoat the parts so I could pull a mold off them. A lot of work… really good to have friends that do this kinda work daily !
Hood
20 year old primer was chem-stripped.

Found sub-primer rusting

So I had it media-blasted

Then body work and sealer.

Then top coat in black
