Now comes the fun part. I made a pattern of the contour of the body and transferred it to a 2 x 4 and rounded the edges of the contour on both sides, This will make 2 lefts and 2 right sides to form the inside lip of both the trunk and the body. Cover the 2 x 4 with wax paper so that it fits tight and nice, tape it down good and use some mold release or car paste wax. Cover with three or four layers of 1 oz fiberglass mat. Make two off one side and then reverse and make two off of the opposite side.
I also need a nice straight one for the front or top of the trunk lid. Use a nice straight 2 x 4 , cover with wax paper and apply 3 or 4 layers of 1 oz. fiberglass mat.
This picture shows all five fiberglass pieces along with the 2 x 4 I used to make the side pieces.
Trim the pieces with a band saw or jig saw leaving at least an inch on both sides. Do this with all five pieces. Use some lacquer thinner to clean up any mold release or wax residue. Take some 36 or 40 grit sand paper and rough up the outside surfaces to help insure a better bond and grip for the fiberglass bondo.
Now its time to put these pieces in place. Take some 36 or 40 grit sandpaper and rough up the inner surfaces of the body and the inner surface of the trunk. Mix up some fiberglass bondo and spread it along the surface to be bonded (mated). I pre drilled two 1/4 inch holes and pre fitted each piece so that when the installation takes place, the bolts will hold the pieces in place until cured. When cured (kicked) remove the bolts, fill the hole and dress up /off any excess. Fill in low spots rough sand and get ready for the next step in part 2.
