Need some help from Painting Pro's
In the middle of a project, painting a set of OEM projectors and the end result is this.....

Idk if you can tell, but it looks like some parts the paint isnt sticking? I did this this morning and it was quite humid so im not sure if that affected the paint. Maybe it was the prep?

So I'm not sure what to do next....Can i shoot more coats on it on a less humid day or just sand it down and start over?

Re: Need some help from Painting Pro's
Yea best to do this right. Just curious, what do you think caused it? Humidity,prep work?

Re: Need some help from Painting Pro's
Humidity can diffinatley cause it. Did you sand and apply adhesion promoter and primer?

And how hard are they to take apart. I would love to do this.

moisture somewhere or improper prep. Did you use self etching primer and adhesion promoter?

Def start over! Humidity can easily ruin a paint job

I just ran into this same problem when painting my engine cover. After 2 days of struggling with it, I ran down to the local paint shop and they were a world of help. Here is what they recommended step by step:

1) strip (I used bumper stripper and it worked fabulously)
2) wash in hot soapy water
3) let air dry
4) wipe down with rubbing alcohol (release agents are used on the molds during the forming process and the plastic can absorb them, the alcohol will draw it out and allow you to wipe away)
5) 2 lights coats of adhesion promoter
6) primer if desired (I chose not to prime and applied paint directly to the adhesion promoter)
7) shoot 2 coats of paint

I think my issue was some of the release agent still in the plastic and lack of the adhesion promoter.

Good Luck!

^^^^^^ this.....

2 adds:

Search for 2k clear. Its amazing. Gives booth result from a can. 2 coats and it same as PRO.

Be very light with adhesion promoter. I like bulldog.

Or I like Dupli-Color Professional Flexible primer. Has adhesion promoter in it. I had good results with this.

Madanio-there's a thread started by Jdubya on how to open these headlights and paint em. Luckily these were sealed with the black rubbery sealant which are SOOO much easier to open than the clear sealant. If you see the black sealant def. give it a shot. If's its clear, i would say forget it lol. I tried opening my stockers with the clear sealant and after 6 hours of fail i wanted to throw it out the window.

Re: Need some help from Painting Pro's
i followed the thread by Jdubya, sand with 400, wash,engine enamel primer and engine enamel basecoat. Was a success on my halogens(in my sig)

thanks for the info griff and Rob, appreciate it!

I sanded those SOB's down and when the weather gets better i will work on one benzel to see how that turns out. If i have the same prob, ill make a trip to get some bumper stripper and bulldog
