Acrylic enamel question
I just finished painting the metal bucket seat backs and bottom skirts of my 67 GTO with Ful-Cryll 2KL acrylic enamel in metallic turquoise. I pre-sprayed all of pieces with SEM Adhesion Promoter. Then, per the online instructions, I sprayed on two medium coats of paint, waiting 5-10 minutes between coats. I used custom mixed paint that was put into rattle cans at a local Lee Auto Parts store. The paint looks great.
My problem is that the paint surface is still just the slightest bit tacky after about 4 days of drying time. The website directions suggest that you should do a final buffing with very fine compound. I would have to do that by hand... no buffing machine. Would that help my tacky surface? Any suggestions would be appreciated. Kerm |

Did you use a hardener with the enamel?
Most 2K's need hardener

Thanks for your reply, Eric. This is a single-stage paint. The hardener is a part of the mix, as I understand it.

Throw the painted pieces out in the sun for a day...Did the rattle can have a bottom section of hardener ..that should have been introduced into the enamel....and then shaken ?

Those parts should be textured steel and are not meant to be glossy, plus you shot them with a single stage metallic paint. All three are reasons that you should not buff them. And being steel, I don't understand why adhesion promoter was used.
MUSLCAH has the rest covered. |

No... no hardener to add in. Tomorrow is supposed to be a sunny day in the mid-70's. Should be perfect for the task. Thanks for your suggestion.

Use a heat gun and get them very warm but be careful not to bubble the paint. Then set them outside for a few days in the sun. Paint thickness and VOC's have allot to do with how fast it dries.

Thanks for the suggestion, Mike. They are much better this evening after a day in the sun. I think I'll repeat the process tomorrow. If they're still not done, I'll try some heat.
