Paint lacquer problems?

[twcullen]

A friend recently bought a 230SLK in bright red. He is not sure but he has an idea the car might have been resprayed. He has noticed in a couple of places that the paint work lacquer seems to be lifting .. He's had chips away look at it and make good where nessasary ...but no sooner than one spot is made good another one appears has any one got any ideas as to what might be causing this and how can he stop it keep happening?

Also a bird st on his car and has made a really big mark and seems to have done something to the lacquer. Any tips to sort this out?

it sounds to me like there was something contaminating the colour layer before applying the lacquer. The only way to stop it would be to strip it off and get it resprayed.

in relation to the bird etching, this can sometimes be impossible to remove. it will be made better by a good machine polish. It may even need wetsanding to get it looking as best as possible without the need for spraying. once this has been done make sure to keep the protection topped up. A good wax or sealant (along with washing the dropping off asap) is essential to prevent future droppings etching the paint.

Just strip the laquer or all the paint off?

it'll need taking right back as far as possible imo to avoid in the future. a good bodyshop will be able to sort it quite easily for you.

The lacquer hasn't been applied properly has to be applied before the paint is totally dry (slightly tacky) if not the lacquer wont take to the paint and slowly but surely will start to peel. If you want it done right its a new paint job.

I've never posted in this forum before, but always have a lurk as I work in the industry.
However, I have to post to say this is possibly the most wrong info I've seen given for ages.
If the basecoat isn't totally dry before applying clearcoat it will cause all sorts of horrible problems, especially when using modern waterbased systems.
That is all.

weso is the best opinion so far. it can be a number of things. could of been damp when it got paint so the paint wouldnt of boned properly. might of been grease which does the same thing and doesnt allow the right bonding. or it might not have been baked in an oven for long enough and not cured.
the only option to solve it properly would be to strip that layer of paint an laquer re-prime the car and start again. if you need a quote dont hesitate to call 07834723978

Weso is right. Water based paint HAS to be perfectly dry before applying lacquer. If not, blooming or bubbling or crazing will occur.

how old is the car? If it was bought from a Mercedes main dealer, you "may" be able to get it rectified under warranty.

Could also be that they have used non compliant basecoat , and laqured it with compliant laquer, which will also flake off ....
Your basecoat deffo needs to be dry , as if not when it gets tacked off you will end up with drag marks everywhere.
