Duct tape





Try taping it together with duct tape and then trying the fibreglass sheet.

put duct tape on the front o the bumper to hold it all into place . then get a soldering iron and stitch the crack but dont let the soldering iron go all the way through th bumper . do this along all the cracks . then get some course sading pper like 80 grit and scuff up all the back of the bumper and the fiberglass should now grip and keep the bumper firm . a new splitter will help keep it more rigid . if this fails you need a new bumper .

been told by k-tech that the bumper is a APC or some think like that plastic and fiber glass wont bond to it and would need a plastic wellder, ok so if if sand the back of the crack to key it and hold with duck tape on the front do you think it will bond this time as have tred doing with jsut figer glass and it jsut seems to want to peel off in one big strip , all so i ve got damage on the pagganger wheel arge iner cover

you aint holding that with just fibreglass.

you need to get the bumper secure and in place before you even look at fibreglass.

you need to make yourself some little rectangle strips out of some old plastic or metal, drill a hole through either end, put the bumper cracks up against each other, drill through the holes. you can then either use self tapping screws or pop rivets. but before you screw or rivet it, use a big drill bit to drill into the bumper slightly to countersink your screwhead/rivet.

when its all in place and your bumper is all lined up and not hanging off, get a grinder and grind all your cracks, it should pretty much melt together, grind it well.

then on the back and front you wanna scuff it all up with p80 and skim the front and back with fibreglass resin (fibreglass in a tin that you mix with hardener(the sheets are a load of b****cks imo, too messy for my liking) you can use the sheets if you like but they aint as solid as the stuff in the tin.

let that dry, grind the front down so its level, then filler it and block as normal
