sorry bud
ive allready repaired the rear bumper once, obviously being fiberglass there brittle and the idiots along my road cant park for sh..
ill send you some photos of the damage, but ill be totally honest with you, even though im a master with fiberglass its a doddle to fix. i just couldnt be bothered because i had my work cut out repairing my boot shut.
you would just need some ally matt, to reinforce the rear of the split.
fiberglass resin & hardner & matting
and a light skim with p38. job done.
whats youre email addy fella, ill send you some photos because i dont come on here much, im a uksc resident
