Well, ya' gotta know that the only thing that makes disasters like this one doable are cheap and plentiful MPC 1970 Bonneville Convertible reissues. That, and the fact that i picked up an MPC 1969 Bonneville Convt junk box with the rear deck section cut out of another example. There's 2 ways i can fix this..... a: fit the 2 pieces together that are pictured, or b: cut the deck out of a 1970 Bonneville donor and make the side joints at the quarter panel top corners. I'm used to doing version b: but i'd give version a: a go if someone can suggest a non-shrinking filler to fill the flaws above the big Vee (on the underside) where the body was thinned to make cutting the deck out. I like microballoons & superglue but it's a little too grainy for the top side of something like this. What powders are you guys using with superglue? talcum? baking powder? Or ?
I'd kinda like to fix the pictured deck into place from the top then fill the Vee on the underside first then level it and bridge the gap with some strip styrene over the Vee. Then fill the little gaps and scars on the top side with what?
