And where were you last week.lol. GMNormally, if you want a nice finish, with perfectly bonds between parts, you wait till your bondo is applied and smoothed before cutting the parts. You'll now spare a lot more time trying to have a nice finish between your parts vs waiting after the bondo stage.
Just sayin .. you know, to help!
It's not too late .. restick those together with clips or epoxy or whatever that will make it "easy" to remove or cut back. As long as you have a solid bond.
People also used aluminim paper in the past, prevents resin to stick to both parts .. but that's when you want to separate AFTER resin stage. You want to go all back to a solid piece before bondo .. then bring really close to a finish state. Cut, and repair the seam line.
PMed you back anyway .. there's no ways that are wrong .. just different road to the end!
Cheers
