I have been asking around, trying to find a good local source where I might could find a primer for resins. I have a couple of projects that I want to build, and both of them are resins. I was told that Plasti-Kote T235 Sandable Primer was a very good primer for resin castings, and that it could be sprayed out of the rattle can with good results.

I have in fact found a local supplier who carries it, "Car Quest" and that would make it very easy to get. I was wondering if anyone has used this primer, and if you have used it, would it be a better idea for me to decant the product from out of the rattle can into a small sealable paint bottle, and then transfer it to my airbrush as needed for more control? Or just spray it onto the resin casting straight out of the rattle can itself?

The reason that I was considering decanting it, is that I had remembered that some automotive primers are thick, and I don't want to cover up details with it, by spraying it out of the can, if this type has those characteristics.

Thanks for all help.

For model building, I mostly work with acrylics, and so I usually use Tamiya Primer. I just spray it right outta the can onto the model.

Tamiya spray can primer would be my first choice. But any of the automotive spray can primers should work just fine. The Tamiya primer seems to go on a little thinner than the auto primers (which are meant to be used on a 1:1 vehicle, so no tiny details to obscure). Plati-Kote is, however, my second choice after Tamiya.

Thanks for the reply Mike. I did in fact pick up a can of Plasti-Kote Saturday afternoon. If I were to decant this primer into a sealable jar, for airbrushing it. What would you suggest that I thin it with? .. That is,.. if it actually needs thinning after decanting ? Would laquer thinner be the correct thinner for it?

Being that is an aerosol, it should be ready for spraying.

Mr Hobby makes a Mr Resin primer surfacer , it's pretty good but then you have to be a die hard Mr Hobby believer to put up with the smell . It works pretty good .

You may not need to thin as Retiredyank describes

If you do need to then PlastiKote is an [acrylic] lacquer
