Priming resin for model railroading

I found that my Tamiya primer did not apparently adhere to my resin train models, even after washing. I will give the cleaning another shot, but am also wondering if I can’t use e.g. Rustoleum primer.
Will be using vallejo paints over the primer, hand-brushing.

You only have to worry about acrylic paints applied over an acrylic primer,you should be ok on that,I can’t vouch for Rustoleum on resin though.

I have used Rustoleum successfully on a resin car model. I used flat black primer on the engine bay and chassis. Looks like The hood and body have a gray primer, I don’t recall whether it was Rustoleum or Testor’s primer. Looks like the Rustoleum gray which is darker than the Testor’s. Can you try a test spot?

I use Rust-Oleum and Krylon both on resin as a primer without any issues. Several different types of resin even.

Immersing parts seems to soften some of them.
I’m trying Army Painter spray primer now.

Jon, I’ve used this before with great success. (On a fiberglass model)

Working with Vallejo spray over Army Painter primer now. Seems to be a stable combination.
