Painting bumper grill - not coming out right

kincaid

Im trying to paint the front grills on the bottom part of a 01 passat…
im using a aerosol gloss spray can ..i rubbed it down but every time i spray it and when it dried it goes to a matty whitesh colour..
also tried satin but fades to the same matty whitesh colour when dry too…
i tried it on a prepared piece of metal( not on bare metal) and still went the same
i thought it was the aerosol can so I got another and the result is the same..
its mixed well enough as shook it well..

anyone any ideas

You'll need to use primer.

did you use any heat ? sounds like a moisture problem

Could be too cold, and too much moisture in the air as taintabird says.

Heat them first with a hairdryer before you spray; then heat them gently after you've applied a thin spray of paint. Build up the layers gently like this.

Better if you can remove the grills of course and paint them in the shed/garage/kitchen etc

use primer first i sprayed my grill in -2c and it looks class

they was painted before and paint started to peel hence why i decided to take them off and redo them i cleaned the grills down completely with fine sandpaper and applied plastic primer with aerosol...i heated the can slightly before i used them to make it flow a bit better too...
then i applied the gloss paint, looked great,that is until its dried and then went all cloudly/whitesh.most of it is like this but parts of it are gloss patches too....
im doing them in the shed and its warmish enough in there..
now ive tried several different types of cans but all with the same outcome...didnt think painting a couple of grill would be so difficult???

You need some aerosol lacquer/clear coat

And also heat the panel to the same temperature as the paint in the can. Warm paint on cold panel = mucho blotchyo crappy finish

i thought the shed was warm but must not be warm enough as i put the parts to be painted in front of some heat then painted them and give them some more heat to quickly dry them and they come out great now..

seems to be moisture in the air that must have caused this before

thanks ALL

Sand the whole lot back and wash throughly with thinners.

get a bucket of warm water and throw your plastic primer, paint and laquer into it and let them warm up.

Make sure there is no grease or any residue on the grill. In a warm area, spray on your primer building up in layers. Spray lightly rather than making it "Wet" looking as this runs and more often than not causes a reaction.

Do the same with the paint layer and the same with the Laquer. Best leave adequate time between coats.

Great thanks

Lack of heat is your problem
as said above
Bucket of warm water and throw the cans in there..Take them out frequently and give them a shake, Wipe off any water from them before painting to avoid water drips..Heat the panel first with a hairdryer and continue to heat whilst it is drying..( NOT TOO HOT ) though...Just keep it warm
