i hope this is in the right section.......having made a side exit exhaust i want to fill the hole in the GRP rear bumper so its a smooth flush finish. the hole is approx 5 " diameter with an approx 2-3" return going back into the bumper. the bumper curves up and down and left to right (compound curve??)
i am thinking about fixing some sort of plate in there and then fibre glassing over that and skimming with filler. i aim to keep the fibre glass and filler as thin as possible to avoid sinkage. . does this sound acceptable?
here's what i mean
