So, yes im all new to this forum, and just saw the 'Hot to make a car hood/bonnet' on YT, and they talked about this forum, so i thought ill ask here.

Im going to make a Ducktail for my 1990 SW20 MR2, and i thought ill ask for some tips and tricks here.

What i thought of was, sanding down the OEM bootlid, and making a thin 'layer' over the bootlid (and making a foam shape of the ducktail)

Naaah...

Apply a layer of clear packaging tape on the bonnet where you want to attach the ducktail. Cover the rest of the surrounding car with release agent or car wax and some plastic sheet. Then lay up a few layers of fiberglass on the packaging tape. This will be the underside of your duck tail. Attach a big chunk of foam and saw and sand to the desired shape. It's really easy, just remove everything that looks like it doesn't belong there . Apply fiberglass on its surface, filler sand spray paint etc until it looks good. The resulting plug is then either used to create molds, or it is reattached to the car and left there.
