front grill?

you will want to clear it too.

that is how you fix your existing bumber.... it should be perfectly fine.... don't worry about it...

its pretty easy to glass and not have bubbles. you also do not make a mold, the correct term if you want your piece to be solid is a "plug" you can make the plug out of anything like glass, foams, etc. you just lay aluminum foil inside of what you want to model, like your grille, then fill it with whatever matieral you decide to use, then you have your copy. hope this helps you.Pete - SPL Enterprise Inc.
