Cracked

[Planman350i]

On my bonnet and rear bumber I've got some fine cracks in the bodywork. One day I hope to have these sorted at the same time as having a respray but in meantime should I prevent the cracks from getting worse by reinforcing them from behind with glassfibre...?

If they are very fine, it may just be paint shrinkage.

I'd tend to agree with Duncan on this one & unless your super proficient with GRP I'd aviod dabbling. If it's the 350 style detachable bumper are the parts aftermarket items which've been resprayed? I've only seen one Wedge with extensive fine cracks and it was on the bonnet of a 450 which after further digging I found it'd had a bump and repair - it looked like an ice rink. If worried about it IMHO I'd go to a GRP competent paint shop to get it re-done.

I think you are not the only one with small cracks, had a look at a few 350's and a 390 before i bought mine and all got small cracks. My car has some on the rear bumper and back side and my brother has some on his rear spoiler.

most people have cracks in their back sides! (sorry)
