that is beautiful. I molded my trunk lid (and regret it) and it's actually still not finished because I gave up on it because it looks like crap,and it's just sprayed flat black now. It would look nice if it were painted to match,but it looks like work in progress right now. I do have the guts to tackle a bumper project like yours,but I'm getting rid of my car,so I'm not going to bother. But seeing work like yours makes me remember why I bought my car in the first place,just to have a bad experience with unreliability and stuff. Oh well....
Can't wait to see your bumper finished. That's the finishing touch your car has needed. Now she's gonna be even more beautiful.
