Painting soft plastic

[ezdays]

You might try doing a test where you set the item aside for the 5-7 days, and check the result.  If the off gasing of the paint continues for 5-7 days, that may be the cause of the bleed through.

Good point Russ, I guess that could be why they say to wait that long for maximum adherence to plastic. I did one other thing, I did find the same primer in white which could help conceal the bleed through. Several coats with the grey did not help, even with darker colors, so I'll give waiting longer a try regardless of which one I use.

Thanks, that's why we ask questions like this.....
