Bumper Fillers

[JPratt]

I have read a lot about replacing the fillers with OEM or Fiberglass. I have OEM front and fiberglass for the rear. The question I have is, are there any tips or tricks that I should know before putting these in? I figured I would test fit then have them painted. Any thing other than that?

Thats about it. Just make sure you are careful when re-installing bumpers...don't scratch the new paint!
