Priming Resin

I didnt think to wash my resin figure and used Humbrol matte white to undercoat. Next figure I will wash for good measure and undercoat with the color I want to end up with since it seems like a waste of time to start with another color. I had no problems with the paint adhering and I did a lot of handling over the course of the project. I used Humbrol enamel with some oil added for shading and highlighting, since I am not a fan of acrylics.

A good washing and any good automotive primer should work fine. I use Krylon, Rustoleum, Testors or any of the other common modeling primers available. THe key being one that has tight adhesion (doesn't lay on thick) and a good eye and hand to know when enough is enough. You want it to conform to detail without filling in detail.

As Rick has said first wash the part well, try to touch it as little as possible as oil from your fingers will undo your "washing" work.

For priming get a good model primer like Tamiya, Gunze or similar.

How well the primer sticks will also depends on what type of resin was used and how well the maker cleaned the part prior to packaging it.
If you want more details feel free to drop me a line.

Thank you for your help. I did not wash the figure, having never dealt with resin before.

First, Welcome to the Forums . Resin must be completely cleaned before any primer is used to remove mold release agents. It's possible the oils on the resin contaminated the primer on your model, as it should have dried over that time period. After cleaning, I prime figures with either Citadel Acrylic primer, in White or Light Grey, from a spray can or with Floquil Grey Primer, an enamel, if using an airbrush.
