Contamination after respray

[cringle]

Hi chaps, a bit of advice if you will. Recently had a small scrape on rear bumper of my 640d. Its Alpine White. Was approx 2 inches around the rear number plate area. The diffuser was cracked so I got a new diffuser and gave it all to a 'friend' to fit and respray. He prepped the chipped area, painted it about 10 inches either side and then put a layer of lacquer over the whole bumper. I picked it up today about 7ish in the dark, but once I brought it home and inspected it in the garage I could see small black flecks, and the odd raised bit of lacquer, in areas of the bumper that were previously fine. Pissed off to say the least. So what should I do? Is there a simple way to resolve this? Or should I fork out £800 and get BMW to supply, paint and fit a new bumper? I'm based in Manchester if anybody can recommend a tried and tested bodyshop who can do a perfect job. Thanks

white's notoriously difficult to keep clean, unless of course your painting in laboratory type conditions.
You wont need a "new bumper" just a key and paint, providing the base is sound.
If your happy with the job other than the specs, why don't you ask him to make good.
You did pay for the job, right?

Paid him £150! He's away over the weekend, i'll have to bust his balls on Monday. So when you say "key" does that involve removing the lacquer and a bit of the white? Or is it possible to just remove the lacquer? Please pardon my ignorance on this topic

+1 even with a spraybooth and all the right kit white can be a right pain in the rump.

It isn't worth falling out over it but I would have thought he should have at least told you about the imperfections and maybe offered to have it back in at a later date to rectify???

as 7even says, speak to him and see what he says

by key, he means just lightly sanding the lacquer with 800 grit wet and dry paper to give the new paint adhesion. then re-colour and lacquer

Thanks guys. I had a good long look and discovered even more contamination, as well as the leading edge of the bumper having no paint at all, it must have been leant on its side and thats been rubbed off completely, this bit was fine to start with! Beginning to wish i'd just had some sort of smart repair done, at least if that had been ballsed up it woulda just been the immediate area! Rant over

If you want to be be sure of minimising the risk of airborne contaminants you have no option but to have it professionally sprayed in a proper booth.
That said, I smart repair a lot of caravans without a booth & providing you're not doing big areas & take care - which means having a few pre-prepared masking tape twists at hand to remove bits & errant flies - I don't have too many problems.
The little 'lumps' you mention in the lacquer are probably just 'nibs' which would need flatting out & then the clearcoat repolishing.

Just give it back to your mate and say do it right.

Should have had the scuff Smart repaired - then the whole bumper wouldn't have needed lacquering

Just to add ..... sometimes it's not contamination. A mix of white paint hardly ever comprises of just white. More often there will be some red, blue, yellow and even black in the mix and despite the very very best filtering of the paint mix sometimes odd spots of unmixed tints come through the gun.
And this isn't restricted to smart or bodyshop jobs nor is it restricted to white cars.
I once got a call to go and look at an SLK - it was brand new and the chap (ultra OCD) had spotted two (smaller than pin prick size) flecks of black in the paint - one was on the rear quarter and the other under the sill!
I asked him if he had taken it back to Merc and he said yes and they had told him everything was within tolerances.
Anyway I politely turned down the job down explaining that if he wasn't happy with the quality of a multi million pound sterile facility where robots applied the paint then what chance did I have

Hi mate. Im manchester based and would happily have a look for you. The secs could be dirt or could be paint specs if its not been mixed or filtered properly. It also sounds like its not been polished very well or at all.If i cant put right right try sapphire garage in newton heath.
