Vallejo primer and resin parts

well I ran into a snag on my Phantom build already. I cleaned the resin exhaust nozzle with water and dish soap, let it dry and then primed with vallejo 77.660 gloss black primer. I am prepping it for using metal colors. it been a week since i ipainted them. Today I put Tamiya tape on to start the first coat of paint and when ii removed the tape the primer came right off. Turns out I can peel it off with my fingernail. I

So the question is do i need to do something different in my prep or do i need to primer resin parts with a non acrylic primer first? Any advice would be reall beneficial.

Vallejo primers do not adhere all that well to styrene, I certainly wouldn’t recommend using it on resin.

I don’t know what folks use to prime resin, I use Gunze Mr Resin Primer and have never had a problem so I’ve never tried anything else.

I will probably do a test shoot with some Stynylrez next time I’m cussing it, er, I mean, working with resin though.

I agree. Vallejo primers are most likely acrylic primers. Garbage to say the least. Enamel based primer is the way to go or use what Greg recommended.

Thanks Greg. I’ll switch to a non-acrylic primer. Will have to see if the LHS has your recommendation.

I have used auto body primers in rattle cans on resin with no problems. That stuff adheres quite well.

I have auto primer for sure. I’m going to try that on the next set of resin parts. Thanks Don

Yes, I’d try that first (Don’s suggestion).

If Don says it works, then it works. And since you have it, lots easier to track down than the Mr Resin Primer, which you’d likely have to order.

I concour with the above, & I like VJ primers for the colours, but I cut it with Future, which ‘hardens’ it a little.

It doesn’t like resin & pe, so prime with Halfords’ (UK) rattle can primer, or Tamiya (!)

Yet to try Styrenz (sp) have heard good things from people I know though.

I use Vallejo surface primers… they don’t do too bad. It helps if you coat which ever part you’re going to prime with a flat clear varnish first. Something to keep in mind about the surface primer… it’s intended purpose is giving something for acrylic paints to “bite” into. Do not expect it to be as durable as an enamel primer. I have read plenty on the interwebnets of guys who were disappointed when they could not sand out any imperfections that were found after the primer went on… that is not the intended purpose for Vallejo Surface Primer.
