Lacquer on bumper

A patch of the lacquer has come off my bumper. Paint underneath is fine, but the lacquer is now missing. How can I sort this, or do I need to go to a paint shop to get it sorted. Car is a 57 plate with metalic black paint (col 298). I don't have any real 'retouch' skills. I'd be a bit scared using an aerosol I think incase it runs and it would cover too big an area. Can you brush on the lacquer (ie with a fine art brush, not a 3" decorators!)?

As ever, thanks in advance for any suggestions.

And on the same theme, is colourmagic Ok to use to mask any light scratches?

Oh Oh. Doesn't sound too good. Brushing is possible and I have done this a few times and got a pretty good finish using the SAAB OEM touch up kit. It is good stuff and has lots of 'body' so you can work up the thickness of the paint.

Spraying an aerosol can is also fraught with other issues, not least the over-spray and cleanup. But you get a much better finish. It would end up looking much better than a brush job but may not be worth all the mucking around. At least the brush method goes where you put it.

I take it you are only talking of the clear coat and the color is still attached to the bumper?

One issue will be the edge where the old lacquer has peeled off the bumper. A very light sand to get the edge to sit back down, sanding into the hole might just do it though. Use a 400 and then 800 grit paper, wet with a touch of washing up liquid in the water.

How big is the peel?

You might well get three to five coats of lacquer on and get it looking reasonable by brushing, and the level might be enough to level out to the old lacquer next to the hole. A decent cut and polish could then bring out the gloss level nicely, but I would wait a week on that.

Don't paint under 10 degrees Celsius either.

A stone chip and a pressure wash will lift the clear coat really fast. Good luck with a claim.[/b]
Yep, that's almost what happened, actually a small scuff from a carpark and then when cleaning yesterday, a 3"x1" section of the lacquer went walkabouts. The paint underneath is fine. No way I'd claim on the warranty for that.

Ok, so paint ordered from Elk, I assume I spray the lacquer into the cap, then brush from there. How long between coats?

My take on all this is that no matter what I do within that area using a brush, it's not going to be worse than it is now and cost more to to right by a pro. As soon as we're into spreaying then that changes.

Had no luck at all with this front bumper. 1 week after I collected it from the dealer a police landrover reversed into it. So the bumper is a new one, only 11 months old.

Thanks guys.

Collywobble,

You're right about the pressure washers. We have Stage 3 and 4 water restrictions, so no home car washing, no lawns and only gardens twice a week on nominated days for 2 hours max. 4 minute showers from 9 liter shower heads using timers.

Car Wash places with the super high velocity low volume heads have sprung up in recent times. I have perfected the art of washing a '5' with less than 5 liters of water in under 3 minutes. And an Estate at that. The lady with the Disco in front of me the other day took 20 minutes!!

I still only use a mit and rinse on and off to keep the volume down, and stop scratching from those brooms the 4WD guys use.

Duncan74,

Buy the spray can. Use the artist brush out of the lid. Use a hair dryer on warm setting to get the panel warm but not hot. Put on one coat and make a 'cuppa'. Come back and do another one the same way. Do this as many times as you want. You may end up doing 5 coats all up. Give it a week, and give it a decent cut and polish and you might be well chuffed at the result.

I did a Megane wheel arch the same way a while back and the paint had been scraped off all the way back to bare metal. Came up so well I can't see the repair unless I am right on top of the thing. No sprayover mess.
