My car has was repainted over the winter by a highly recommended body shop. Its a dark pearlescant blue with lacquer.

I have driven the car just 1200 miles since and it is covered in chips all over the front, many many more than it gain in the first previous 17000 miles of its life. The car is 17 years old and the body shop say I have to live with the chips as modern paints chip easily because they are so hard.

Is this right? My other cars both modern have nothing like as many chips and have done 60 times the milage the repainted car has done since its paint job. The chips on it really show up as they are white.

My gut feeling is that the paint job is not acceptable but am I asking too much? its a low car and I know they are prone to chips, but this seems excessive.

The thicker the paint the more can be knocked off by a stonechip & the more you will see. Common on cars that have had the normal impact areas resprayed.

The whole car was stripped back (its GRP) a new base coat was applied and then paint on top. I would expect it to perform like a new finish rather than a resprayed one. I saw the gar during the process and it had been sanded right back so there was no paint remaining. Would this mean that the paint wouldn't be excessively thick?

Was the car hand-sprayed at the factory?

A robot paint line can be programmed to lay down so many microns of paint. The manufacturer obviously has a sound financial interest in putting down the minimum build of paint products required to support their bodywork warranty.

Any hand-sprayed paintwork will have a much higher build of paint than an automated factory finish. All repairs, throughout the industry, are hand-sprayed.

The choice of clearcoat will also make a difference to how susceptible to chipping the new finish will be - as can the substrate layers. "Rubbery" finish is less likely to chip (which is why sills are often sprayed with a rubber 'stone chip guard' finish before painting) - but can be more susceptible to other kinds of damage.

It was hand sprayed at the factory. The new paint is the same colour, and is apparently a Saab paint.

Probably down to a different clearcoat being used then...

So. Do we think the body shop should try and fix the problem?

You could ask, it wouldn't hurt. I don't know of any bodyshop that warranties their paintwork against high-speed impact by sharp bits of rock, but if the rate the car is acquiring damage is really not commensurate with typical use, they might be prepared to do something as a matter of goodwill.

If my car was covered in stone chips not long after a respray whilst in normal use, I'd ask some questions. I've not spent all that money for nothing after all.
