Lawson try eagle one wax as you dry stuff works well dont leave the white resdue eather and works well try it on your reg driver then see if you like it .
Ten years ago i built my first 36 used all the EMS parts that they made and i agree the hardest part to get rite was the rear fender .Just my humble thought after all it was my first car.
Theres a easy way to strip that works well . I use paint stripper and a razor blade then a twisted wire brush on a dewalt grinder i found it to be easer then sanding pluss the striper has a metal protector in it so you wont have it rust back over in a day our two.I have done 2 cars this way...
