Scalefinishes says there basecoat and enamels no longer compatible with tamiya primer?

Every so often, someone here or elsewhere discovers an enamel primer, when they try to shoot lacquer on top of it.

The cheap store brand primers, and the basic Rust-Oleum (non-automotive) primers are enamel.

Now we're getting somewhere.  Thanks!

You don’t have to look too far to find enamel primer.

Or, at least you didn’t used to have to.

I had Scale Finishes enamel clear wrinkle their lacquer on a build recently.  

Took all the proper precautions I normally would with a hot lacquer, and the primer and lacquer coats were fine…but the enamel wrinkled the lacquer.  

I stripped, reshot and used a different lacquer clear, no problems - but I’ve got to wonder why they’re apparently using such hot solvents in their paint that even careful application could case this to happen.  

I mean, they’re mixing the paint themselves, why not mix with reducers that are actually suitable for the task?

Same, even, with the lacquer color coats.  Why mix them so hot that they can wrinkle and ruin styrene if an unsuspecting person doesn’t use exactly the right primer?

DISCLAIMER: I know many of you get outstanding results with these automotive paints, and I’ve had SOME success with them too, but it’s certainly not as easy as it could be…

It seems like the newer Tamiya primers (made on the last 6 months or so) are having issues with my paints.

I recommend that you test whatever primer you like before you use my paint over it. 

If you have any questions or concerns, please email me scalefinishes@gmail.com

Whenever you try mixing materials from multiple sources...painting, resin casting, whatever...TEST FIRST before risking something you have a lot of time and/or money invested in.

Particularly true when painting a 1:1 car...just one look at the cost of the materials should convince anyone...

I use Speed Shapes when I am experimenting with any sort of paint and primer combo. IMO plastic spoons are too small and not enough surface area. Example the spoon does not craze. Then you paint the car. Parts of the hood crazes and nothing else. The Speed Shapes are only a couple of dollars. They are as a big as a 1:24 body or a little more.

Someone commented on the newsletter video that there was a recall but I havent been able to find any info that supports that.

Mr Hobby's Mr Surfacer primer will work fine for Scalefinishes base coat paints, and is a good substitute for Tamiya,   I feel that Mr Surfacer primer is just bit better than Tamiya primer.

I don't know what the issue might be, but I've used Scale Finishes lacquer base coat over Duplicolor primer on numerous occasions.

They're probably just trying to avoid complaints about incompatibility, even if it's not necessarily a problem.

You know how people can get when they screw something up.

They like to find someone other than themselves to blame.

This way they can say "I told you so".

 

I'll still be using the same primer I always use.

Call me a risk taker!

The Duplicolor primer is very good.  Been using that primer since 96.  I've sprayed Imron, Centari,  PPG and  Duplicolor laquer paints over the Duplicolor primer base numerous times.  All good results.  Just my opinion, I think this primer is much better than Tamiya, Testors, etc primers.

So you are implying that the speed shapes are made from the same polystyrene plastic as model kits? I have feeling that those speed shapes are not polystyrene, but I'll be happy if I'm wrong.

As for plastic spoons, you have to select the correct ones.  You need to find the ones made from polystyrene.  The recycling symbol is "6".  Majority of the inexpensive plastic spoons are polystyrene. They are also fairly brittle.  But you can also find spoons that are much more flexible, made from Polypropylene. recycling symbol "5".  Those are not affected by most paint solvents.  To make things even more muddy, there are multiple formulas of polystyrene out there (just like for model car kits).  Some are more resistant to hot solvents than others.

I agree.

And the fact that virtually any lacquer used over it becomes easy to strip with Super Clean is a bonus.

I never have any worries whatsoever that I will have any difficulty removing a paint job should it become necessary when using Duplicolor primer.

I disagree with Dupli Color primer being better than Tamiya. I used to use Dupli Color and since I do mostly customs, I was always fighting ghosting issues with it. It would cause crazy glue, putty and joints in the styrene to shrink. Not to mention that it doesn't lay down nearly as smooth as Tamiya or go on as thin. One is made to go over styrene. The other is not.

I used some tamiya white primer on current build I'm doing and it is amazing stuff.  It does lay down silky smooth and self levels amazingly well.  Mr surfacer thinned right with either MLT or rapid thinner it's the same if not better.

I guess that’s why the call them “opinions”. 😊

Not opinions. Facts from experience. When I spray Tamiya over any model (no matter how old or new), I don't have to worry about it crazing the styrene. Can't say that about Dupli Color.

 My point is that there is not enough surface on a spoon to get an accurate feed back

We've developed this massive, high impact Polystyrene Speed Shape to give you the best possible surface for testing and display. The larger surface area and curves, over our original Speed Shapes, will help bring out some of the colors and finish details that could be too subtle to notice on the smaller shapes.

I can see where these would be very beneficial. Especially if one wanted to test color combos. I've seen them before and have meant to get a few to have on hand. But, haven't yet.
