The gelcoat on a 35 year old fiberglass engine cowl (hood?) on a small airplane is cracked....basically covered with spider cracking. The part is approximately 3' wide x 3' long. Given it's age I'm fairly certain it's polyester resin / E-glass construction.
I've read the paint mfg's P-sheets and believe I have this correct but I'd really appreciate some feedback on my proposed repair/refinish method. Below are the basic steps I'm considering:
Sand off old, cracked gel coat.
Apply new gelcoat (Evercoat OneStep) with a PreVal sprayer.
Fill low spots (Evercoat Rage), block sand w/ 80 grit.
Prime (PPG Shopline JP371 epoxy primer - White).
Primer surfacer (PPG ShopLine JP202 2K Primer Surfacer), gide coat and block sand w/ 80 grit.
Glazing putty (Evercoat Glaze-It Finishing Putty), guide coat and block sand w/ 220.
Seal (PPG Shopline JP371 epoxy primer - White) reduced to use as a sealer.
Topcoat (PPG JAU Direct Gloss Acrylic Urethane - White).
