Vinyl Kit priming

#1 Post by weird_oh84 »

Hello everyone!

I’m getting ready to paint my first kit — it’s a Steve Wang Gillman bust from the 90’s and its cast in Vinyl.

Can I use Tamiya Fine Surface Primer to prime it or is there a better primer to use on Vinyl?


Thanks for the help!

I have always used Krylon gray primer on vinyl. Just remember to wash the vinyl with dish soap BEFORE priming to get any of the mold release chemicals left over from the casting process off the vinyl surface. :wink: A VERY important point that I did not know about 20+ years ago when I got back into The Hobby.

Good luck!! :thumb2:

Do *not* use any enamel based products on vinyl - they will never dry. In general it's best to avoid anything that is not acrylic. If you are not sure, test on a piece of scrap and leave for a few days.

Automotive acrylic primers are great, or failing that purpose-made primers like Stynylrez are fantastic for airbrush priming.

I have had really bad luck with vinyl, but rule of thumb is lacquer based primer for vinyl. Always test on a piece of scrap first.

I've used Tamiya spray primer on vinyl successfully. On vinyl, your color coats have to be acrylic; enamels won't dry at all.

If you lay down enough acrylic or lacquer to form a barrier first, then enamels will work. But it is better to play it safe.

I always test my primer on the scraps that get cut from the vinyl. It's better to have the primer not cure on those parts, than on the actual kit.
