Paint Help

[featherfoot]

Hope someone might have 'experience' opinion on a paint problem on my car.
At the beginning of this year - after a spot of sheep worring - needed a new bumper and bonnet, which my local dealer sorted for me.
After 6 months I noticed that while the bonnet had maybe 2-3 stone chips in it, the bumper had hundreds peppered all over. It looks as if I follow gritters for fun or have driven on freshly top gravelled roads............My car does about 60 miles a day, mostly on v. rural roads following no one! And no to the gritter following theory.
Paint company says nothing to do with them (not that they have seen the car) and the dealer-whilst admitting that far more chips than average-isn't very forthcoming....
I know trading standards is an option, but don't want to ruin any relationship with dealer all together
I asked about plasticiser in paint and was told that the manufacturers supply it ready to paint straight onto bumper, the paint isn't flakey but seems to chip every time a fly hits it
Any help gratefully received
Regards
Iain

Sounds to me like hardener hasn't worked. Bumpers tend to be sprayed with a primer ,basecoat and then finally a two pac type clearcoat then in through an oven for 30mins/hour about 80degrees (cor sounds like cooking program)
Many people claim that you don't need an oven or heat lamps to bake paint/clearcoat off,

Personally being envolved in the painting of cars and bumpers for last 13years albeit in a carplant (honda) have always found best results achieved by use of ovens/lamps.

Many parts get resprayed on new cars if damaged on production line and the processes they use to repair them make them new.

I would insist that the spray shop examine the bumper, and see what their answer is.
You could even take it to another spray shop and ask for their opinion.

I had a similar problem with my front bar. Following respray by VX the paint has peeled off around grill and bits falling off in large patches around stone chips......very poor indeed!

as I understand it from speaking to the owner of a "good" paintshop/repairer the problem they face is getting enough temperature onto the parts being sprayed to "bake" the paint as it would be done in the factory - limit to how hot you can heat a fully road ready car without damaging other components!! Hence no matter how good the paintshop is you will always end up getting far more damage done to resprayed panels, unless of course the car is stripped back to the shell at which point they can heat it to far higher temperatures and achieve a finish close to factory.

Thanks for the answers so far
It was an independant who said to take it back to dealer as was not acceptable....Dealer has seen it but is saying nothing wrong with paint and must just be chips...trying to avoid a respray?????
Don't they spray bonnet and bumper before fitting to car?

wouldnt imagine so, not if they are having to blend it in to the wings.
