I didn't really notice it, but Im using my driod. How did the backside turn out? I havn't had any expierence with any over cure issues. If the shine is the only thing affected i wonder if you could bring it back with a cut and buff? I know you could probably do a recoat, but I dont think I would seeing how good it looks, especially if its in a location that will not be noticed. Guy do you have one of those laser thermometers? I use mine alot during the pre- bake cycle to get an idea on how the part will heat up. Sometimes I have to back the oven down a bit after flow out to maintain the proper cure temp. Just remember you will be your worst critic when it comes to your work. I think it looks great.
