Some Info About Painting With Enamel.

first of all.....you mention you painted your dash and you also mentioned something about plastic adhesion .....so what did you paint? your dash? or your dash pad?

when it comes to plastics,vinyls,fabrics and so on....I suggest cleaning them well and using a scotch bright pad to dull down the surface and then use a rattle can of vinyl and fabric dye... about $5.00 a can and does great.

as for if you painted your dash, why did you rattle can it? the finish of painting with a paint gun is much nicer and you can "dial in" the ingrediants to make it cure to your liking and weather accordingly.

if you are having troubles with the paint curing maybe you should try letting it sit in the hot sun for a day or waving a heat gun over it for awhile.

I personally used an oil based paint to paint my dash. It "said" not to thin it out with any solvents but I didnt care what the can said lol..... so what I did was mixed up the paint 1-1 with medium reducer and then splashed in some hardener into the mix ,pulled out my hvlp gun,set the pressure to about 12 psi, laid a "tack coat" which is a light dusting to give a base for future coats to have a little extra to stick too, then I went through with "cover coat" medium coat. and then I came through with a final coat "wet coat" which is just enough paint to give it a glassy look and evenly covered surface.

I have been using the oil based paints on the interior of my duster so far with AWESOME results. I normally am not a fan of oil based paints due to the slow dry time but when you add reducer and hardener it starts setting up in minutes and is dry to the touch in about 2 hours "tacky" and is cured in about 5 hours and is hardened in a matter of days. and this process is faster yet in warmer weather/in a booth/sitting in the sun.

I also used the vinyl dye on my plastics/vinyls in my interior and have had great results.

I agree as has been mentioned above that your paint work is ONLY as good as the prep time you put into it prior.....and you must either know what you are doing or do your research ahead of time so you do not run into problems such as that......and when in doubt,spray a test spot ahead of time to make sure you get the results your looking for.

if worst comes to worst and you do not have access to air guns or compressors and so on and rattle can is your only option, I suggest scraping it all off,cleaning the surface and re prepping it and repainting with a different rattle can paint .

heres a few pictures of what I did with mine.
