"Spraying Battlefront Resin vehicles" Topic

I hate resin vehicles.

No matter how many times I wash them, I can never get all the mold release off.

I just tried, again. I am using hot water and dish detergent with a toothbrush to scrub into the corners ans such. Washed twice. Rinsed under running hot water. Dried thoroughly. Spray with Army Painter desert armor color (British vehicles). Paint starts to do that 'pooling away' thing.

Grrrr…..

So I tried shooting with my preferred undercoat for metals, black Krylon primer. And lo and behold, no problems. I think I have solved an old problem for me – hit it with the plastic approved Krylon primer and then go back with the real undercoat color.

Just thought I would share.

I have been using Kylon primer or like products for about 20 years now.

Hmm, I have never washed any of the BF vehicles I have bought (and we're talking hundreds) and I have never had that problem with priming them. Weird.

Whenever I wash them with detergent and hot water, they frost up. I have no clue why.
If I simply rinse them with Very Hot Water™ straight from the tap and with the sprayer, I get no frosting.

I prime with WalMart Flat Black, the $.89 USD can. I have never had any problems since.

Army Painter has always caused me grief when used as a primer. I don't have a clue what the resin type is called, but Khurasan warned that their initial run of Caiman's used one of the problematic resins, and advised using auto primer first. I've since used it to great effect, though it does go on a bit thick.

Never had an issue priming and spraying Battlefront resin models UNLESS using Army Painter sprays. I suspect the problem is at the Army Painter end of things.

Thanks for the tip, I'll be doing some soon.

I've never had any problem with them either. Most of the time I was them with the same chemical the OFM referenced and the same primer to prime them. Sometimes I've forgotten and just sprayed them. Never had any problem either way.

I would guess that the army painter is the problem too. Try the cheapest spray paint you can find as a primer, it will work better.

+1 to no issues. I regularly use Army painter Soviet armor and the early war grey and lighter gray as a base coat and primer and I never rinse the BF resins. I have had to wash other company's resin parts when they felt oily, but still no issues.

Luck of the draw maybe?

I have had mold release issues before from scenic companies and such, so I know your grief…

…auto primer first… though it does go on a bit thick

The chap in Halfords (UK retailer of car parts) proudly told me that they had reformulated the primer so it went on thicker and covered over minor scratches and dents. He seemed very confused that I wasn't happy about that… I now have to spray several light coats to avoid filling in the detail.

I've never had that problem, I've used Humbrol mattb black, and now Tamiya sprays and theyve always come out nice and evenly.

Having recently returned to the world of resin models for the first time since making the leap from enamels to acrylics, I was not sure what would work.
However I have used a spray can of Humbrol acrylic grey primer, which seems fine.

According to Evan, BF's sculpter, they do not use a mold release on their resin sculpts, and he has never washed any model before painting. I have no way of challenging that, but I do believe I've had models where maybe the resin had not cured properly. In any case, I've always used Rustoleum's Painters Touch line of primer to good effect, particularly the dark gray. It's not quite as thick as their Sandable Auto Primer.

When I wash the models frosting appears
Solution – do not wash them
Never had any problems after that

I had a lot of problems with a single set of BF aircraft (P-40 Warhawks) taking primer, but other than that I've used Krylon "Ultra Flat Black" and now Rustoleoum "Camo Flat Black" without issue on the BF ground models.

I have been washing the models, and getting some "frosting" but that never impacted the hold of the primer. After reading the above notes I guess I may just abandon the pre-primer wash all togther. That will save a step in the process for me.

I never washed the resin figures. But I do wash the plastic ones. I wait till my wife is out, then put them in the top row of the dishwasher, and set the cycle to light wash.

I use Formula 409 Orange to clean/degrease/whatever all the resin that I paint.

It takes a while, several scrubs and rinses (along with a weeklong soak), but when the detail side of the model is rough like a stone (or the cut face of the resin), it's ready to soak up paint.

PHGamer, you are a class act :-)
