well i couldn't wait too long to get started, so i opted to finish the front bumper, i started by sanding the openings, with some 60grit, to make sure that all traces of paint were gone, and that the plastic surface was nice and rough, then i drilled some 8mm holes, around the edges of the opening (not shown), this is so when the fibreglass is spread onto the sides, it sqeezes thru the holes and acts as extra grip, to ensure no cracking l8r down the line...
i then trail fitted them (good job i did) as the fit was fairly poor, so i held them into the right position, or the 1 i thought looked best, then stuck some holding screws in, to hold them in position, while the fibreglass dried......
after a nightmare of sanding sat on the tile kitchen floor for a couple of hours....
i gave them a coat of filler, and then repeated the process, then gave them a quick prime, outside in the dark to see what they look like, i'll finish them to my standard tomorrow, with some 2k stopper and high build primer, but heres a couple of pics, gives ya the general idea......
