Can I get away with using Tamiya primer under Dupli-Color touch-up paints?

[Monty]

I came across a couple cans of Dupli-Color that I really want to use, but I'm wondering if I'll have to use 1:1 auto primer to protect the plastic.  I was hoping Tamiya lacquer primer would be sufficient, as it goes on thin and doesn't bury details.  (I'm assuming auto primer might).

The Dupli-Color sealer primer 1699 also goes on very thin and is compatible with the kit plastics that I've used it on.  Beat to test on a kit part that your not using.  I'm not sure about the Tamiya primer under the Dupli-Color top coats.

I’ve never had issues spraying Duplicolor over Tamiya. Not that it won’t happen, but so far, for me, no issues.

I can't think of any primer that goes on thinner & hides less detail than Duplicolor sandable primer.

Their primer sealer is great too.

I use somewhere around 5 coats of it on every project.

And it's a heck of a lot cheaper than Tamiya!

My only caution would be to use very thin coats, at least to start.

Duplicolor primer is hotter than hobby primers & will craze if sprayed on too wet.

Same here. 

The only thing I've noticed with Duplicolor, is that while it goes on thin, you'd better be leaving lots of flash time between coats.

I usually allow about 20 to 30 minutes between coats.

Is that what you mean by "lots of flash time"?

Same here, no issues for me using Dupli-Color over Tamiya primers. I have found through my own experience that Dupli-Color, Tamiya, Testors, Black Gold, and MCW paints are ALL compatible.

Yes. I've had a few interior pieces show cracks in the colour after a while, after the primer gassed out. That's pretty much a guarantee that there was an issue with the undercoat, in this case, the primer. I tend to rush small stuff when priming... ;(

Been using Tamiya Primer under DuPont automotive lacquer for at least 15 years and never had an issue.  I really thin the heck out of my Dupont stuff(6:1) with their lacquer thinner which is really strong stuff and Tamiya primer stands up to that, so I wouldn't worry about any lacquer over it.
