Yellow primer?

[aurfalien]

Hi all,

Would you recomend a yellow primer for any final color?

Since I'm going to have a few yellow projects, I was thinking to get a yellow primer as yellow final coat is a PITA!

I understand that a white primer would help but a yellow primer would in fact be better.

Anyways I would prefer any money spent to be long lasting so if a yellow primer could be used for any final color, than its a home run.

Thanks in advance.

PS If you have painting yellow tips, I'd love to hear em as well.

If you're airbrushing, you can use Model Master Insignia Yellow as a flat yellow primer. But you'll still need to lay IT over a uniform coat of white or light gray primer.

Floquil had a lovely flat yellow called Reefer Yellow, but of course it's now defunct. I grabbed a couple bottles to use on airplane propeller tips. How I miss Floquil.

I used to use yellow primer all of the time!

I absolutely loved the stuff!

Just can't seem to find it anymore.

I believe it's called "Zinc Chromate" primer.

I used it under almost everything, but it works exceptionally well for yellows & greens.

Cool info, thanks Richard!

I've been looking for zinc chromate because I had sprayed it on my 1:1 TR4A and am doing a model of it. zinc chromate highly toxic, it is also a carcinogen which explains why it is difficult to find now.

Here's a few sources I found but haven't tried any yet ..

Great info.

Curious, is it any more toxic then lacquer based paints?

Yeah, you might not want to get too involved with it.

I used it for a short time many years ago when it was available at local auto parts stores.

I assumed there was a reason why it was no longer available.

Ok, I'll stick with Tamiya white primer then.

[russosborne]

If you are airbrushing, could you tint the white primer with a bit of yellow? I really don't know if it would work, just bringing it up for discussion.

Curious, how long do the spray particulates stay suspenedd in air for?

And what kind of fiters would be suitable for Zinc Chromate?

Wikipedia had some interesting info on Zinc Chromate, kinda scary.

[Snake45]

Zinc chromate is used to protect aluminum and other metals from corrosion. Completely unnecessary on plastic. No need to mess with it!

Years ago, when I used to own a body shop and we used to paint ANYTHING, including heavy equipment, much of it was yellow, such as Cat, Case, Dresser, JD etc. Then, somewhere along the line, the paint makers were mandated by the EPA to reduce the lead in paint. POOF, there went the opacity in many paints, but especially yellow. We used to be able to paint Cat yellow over black primer, and it covered in no more than two coats. But when it went lead free, it all became transparent. So, we started using Dupont Vari-Prime as a base coat for the yellow jobs. It worked quite well and covered better than a gray primer base. I have also used tintable primers, but my memory doesn't remember what brand. PPG also made a DP epoxy primer in yellow. I also used to have an endless supply of paints for my models, as I used everything that the real 1:1 jobs did. But, those days are gone. So, I now use Mr. Surfacer 1200 or 1500 as a base, followed by any Model Master flat yellow, such as Dunkelgelb. Then the yellow top coat, applied in thin coats as even then, it must be built up. Progress is NOT such a good thing!

[StevenGuthmiller]

I used to like the yellow primer mainly because it seemed to cover so well, dried completely smooth & was not "hot" enough to damage the plastic at all.

I've tried a lot of primers since those days & have yet to find one that I like better.

A little something I found by an Amazon reviewer of VHTs product;

"VHT Prime Coat is a great line of primers by VHT that comes in multiple colors of which Yellow Zinc Chromate is one of the color choices. Although it is a very good description of the color, it contains no zinc chromate. VHT is not hiding this fact as has been suggested. You can go to the MSDS on the VHT website to see the list of ingredients for yourself. I would've given this product a higher star rating (because I have used VHT primer and have been very satisfied) but it irritates me that I had to dig so deep to find out it didn't have zinc chromate as an ingredient."

So the VHT Prime Coat in Yellow Zinc Chromate color does not contain the highly toxic zinc chromate chemcial compound.  I confirmed this by reading there MSDS (Material Safety Data Sheet).

There site even suggests that its apllicable to most plastic surfaces.

I contacted VHT and there zinc chromate colored primer is a Alkyd Enamel formula.  No zinc chromate compound at all.

I used rattle-can zinc chromate primer once, years ago, because I asked around and a number of people told me it stuck to aluminum better than other primers.  I don't know if it actually works better, but it is still sticking to the piece I sprayed with it.  An etching primer might work as well or even better, and you can get that in spray cans.

With all this talk of "yellow primer", I'm surprised nobody has mentioned "Used Cars"...

I've heard tell that Tamiya Fine Surface Primer in pink works just as well for yellow as it does for red...

There's no need to get actual yellow zinc chromate primer. you can get Model Master Acryl 4851 - ANA 627 Yellow Zinc Chromate.

You can also use Vallejo Model Color 70923 Japan Uniform WWII and Humbrol 81 Matt Pale Yellow are good too.

An advantage of air brushing over rattle cans.  I don't have an air brush yet...

I no longer wish to incur the wrath of my lovely wife.

[SfanGoch]

Tell her to go buy some shoes, a bottle of Bond No. 9 or a designer bag. That way, she'll be an accomplice in "wasting" money and she can't complain about some crummy airbrush and compressor. Works for me.

Question is, are you going to spray Automotive lacquer over acrylic paint?
