I'm painting my EL grille and my chrome number paint surround heritage green to suit my car.

The number plate was fine, but the grille turned out rubbish and i have no idea why.

For both of them i sanded the surface, wiped it thoroughly then applied three coats of the primer in the picture.

As soon as the paint hit the grille to spots 'formed' on the surface. I also have put on one coat of the clear coat on both.. assuming i'll have to sand it off when i'm trying it again?

What can i do, and why has it happened? I have painted many plastics before and not come across this problem.

Plate surround which was fine:

Grille, not fine:

are you using all the same cans from the first batch of painting you did?
Definately looks to be a contaminated surface onto which you are trying to paint.

Tried shake up the heritage green can a bit more?

Looks like it has had wax or silicone on it at some stage, I would say you will need to sand it back, then give it a good going over with silicon-off or a good wax and grease remover then try again.

If there is wax or silicon on the surface it wont stick and cause exactly what has occurred....

Clean off with a wax/grease remover after sanding. Make sure you shake the cans for a few minutes prior to painting. Best to spray a few light coats of primer, let that dry for at least 1 hour if warm weather. Give a light sand with 600 wet & dry and allow to dry. When applying colour do the same, apply several light coats, same with the clear coat if used and allow a day to dry before putting back on the car......

I agree with the above posts, looks like there is something on the surface preventing the paint from adhering properly, I've had similar things happen with a few plastic things I've sprayed before. Sand it back and go over it real well with wax and grease remover, let it air dry for a bit, then spray on a few very light mist coats and see if you still get those problems.

Ahh yeah, wax seems likely. Haven't owned it for all it's life so that's probably likely!

rub it back...clean with wax and grease remover then apply a medium coat to start with...the wetter you put the paint the more chance silicon will re appear..

Yeh wax/grease remover before paint mate.

It's called fisheyes, basically only needs 1 small grain of silicon to do each 'eye'

there is a 3rd way around heavy silicone contamination,as you sand it still spreads and many wipes with prepsol,reduces it.use a alcohol based isolator coat to seal it and lock it up,then use u-coat and fill.DONT break that seal coat.car repairs and car yards try to match panels and use all types of polishes to sell the cars.
