Fixing my front bumper as its cracked to **** from being so low. Looking to firbreglass the inside, is this cool to do on a plastic bumper?
Also, will need to put filler on the outside and smooth it down so I can paint / laquer it. Could I use filler/primer spray to do this, or should I use the paste stuff that you spread on, then sand smooth and prime after?
If I could I would rather use the spray filler/primer, but what ever is best, just say the word.
