Does lacquer peeling = respray?
Discussion
To repair it properly, the lacquer will need to be sanded back to the point where it stops lifting, then either a local paintjob or a larger full panel & blend, depending on how bad it is.
It may be possible to lightly flat and polish the edge of the lacquer to make it less obvious, but it all depends on how bad the affected area is, how perfect you want it & how much you want to spend.
There is also the risk that if the lacquer is peeling because of a reaction to the underlying paint, or poor quality lacquer was used, or the base was left too long before clearcoating, it will all need to come off...

This is what happened to my Leon, it got so bad in the end that I ended up peeling the laquer off almost completely just using a hosepipe to rid it of its flaky skin condition!http://www.youtube.com/watch?v=e3U9Ss35atQ
The laquer seemed to have lifted wherever it was most exposed to the sun, the only places I couldnt get it off were the lower half of the doors/wings and all the plastics. Unbelievable on a 7 year old car

They apply laquer to the base coat before it's fully cured though to make it bond properly, otherwise you'll most likely end up with the above video, so I don't think any reputable bodyshop would entertain doing it.
I see what you mean but they key to base coat when they blend Edited by LocoBlade on Friday 14th May 23:49

I'm not too sure what you mean here. When a panel is blended, you need to lightly key beyond where you intend the new lacquer to finish, but you are actually keying up the original lacquer, not the underlying basecoat.Personally, no matter how good the basecoat looked after removing the failing lacquer, I would never just key it and apply a fresh coat of clear. You never know how good the basecoat is and if its been exposed to the atmosphere/UV sunlight etc, it is likely to be degrading as well. I would always sand away the damaged lacquer, and thoroughly sand the basecoat, then apply a fresh base and new lacquer. You may well find someone happy to just give the damaged area a fresh coat of lacquer, but if its of any sort of size, dont be too optimistc on its durabillity...

Interesting, thanks fellas.
What's the going rate to spray a couple of doors and a bonnet do you think?
Difficult to quote blind. To do a bonnet, there's a good chance it'll need blending into the front wings, if you're doing both rear doors, you'd need to blend the front doors & maybe the quarters too. Before you know it, you've painted both sides & the bonnet...What's the going rate to spray a couple of doors and a bonnet do you think?
