Shaping convex body panels ....
So I'm filling the factory roof seam after cleaning and sandblasting - factory used some lead and some filler - I used short strand glass and finishing up with polyester. I'm having a real time with shaping this "outside" or convex curve. I need to learn how as this will not be my last rodeo - how you guys work with "bubble" tops and fat fendered cars and get 'em perfect is magic. I can handle a straight , flat body no sweat (66-67 Fairlanes, Novas, Chevelles) but I need tips on shaping these types of areas as this is a first for me. A link to any videos known of would be great ! This is my own car, I'm just a weekend warrior.
