Primer for resin?

[crowe-t]

What's a good primer for resin parts?

I tried some Duplicolor Filler Primer but it didn't adhere too well.  It could have been some mold release on the resin.  I'm thinking Tamiya Fime Surface Primer will work better on the resin.

Two possibilities here. Either you didn't remove all of the mold release or the caster used cheap resin. Get some Duplicolor self-etching primer. AutoZone and Pep Boys carry it.  You also might want to wash and scrub the parts again with dishwashing liquid and wipe them down with acetone (not nail polish remover) before using the self-etching primer.

Wash the body with warm water and Dawn dish soap. I use this for all my resin projects. I use a old toothbrush to scrub the parts. Small stuff I just wash in the palm of my hand. You can strip off the old primer with this paint remover. Stuff works awesome

I tried priming with Tamiya Fine Surface Primer and it adheres very well to the resin.  Since it's formulated for plastic models it seems to adhere better to resin too.

Clean the resin good with detergent or what the other guys recommend.   I use Duplicolor scratch filler/primer with good results.

Like most of the others here I will clean the Resin body or part with Dawn dish soap before and after any body work that is needed. I have been using the Tamiya primers with good results but the last couple of Resin builds I have started using Automotive type primers and feel that they maybe just a little bit better for the first coat of primer. After that I go back to the Tamiya primers and what every color coat I'm going to use. If you are not already doing any sanding or other body work on a Resin model away from your normal work area I suggest you start.  The dust from sanding Resin can and will get on other components and give you problems with any future paint work.

Allot of resin builders use this to prep the body.
