Another tip I always paint bumper cover as if they are on the car then let the clear get sticky and then lay it down the build up on the edges won't happen
Yea I did use to do that with putting the bumpers on panel stands maybe start again.were always learning different ways gteat to hear how you approach it.thanks gor the comment
When I do those type of bumpers I wont take my first coat of clear to the fine line,on my 2nt coat i take it all the way just a tip i picked up doing these because they bridge so easy after the 2nt coat i take the tape off before i bake.
