Stynylrez SNR-401 Primer, 4 Fl Oz (Pack of 1), White, 4 Ounce

I bought this primer in white only because I intended to paint pearlized white over it as my base coat and that is semi transparent. I think I will get some gray and black as well along the way. Anyway, the long and short of it is I really like this primer. I've used it on plastic and on wood so far with good results. I do find I need to thin it a bit to be able to layer the paint and build it up as I want it vs blasting on one thick coat. I thinned it with my own thinner I make up, I cut the primer maybe 15-20% or so and it sprays out of my Badger 200 with a medium nozzle very smoothly. It will spray straight from the bottle with the right needle and air pressure though and self levels. I lightly scuff plastic parts before priming for added adhesion as a safety net fwiw. I've edited this review now to five stars because this is now my go to primer.. I have now sprayed even lacquer paints over it with no issue . I've added craft paints to it to tint it slightly and that worked fine too. Because of finding I can tint it I haven't bought the other colors yet but I'm here to buy it in black and figured I would update my review while here.

I use this in my airbrush to prime my resin pieces before painting. Does not need to be thinned, quick drying and lays flat. Best of all it is sandable to a very smooth finish.

I’ve been painting scale kits and wargaming miniatures for a long time but I never got around to buying an airbrush primer until now. Very happy with the result from this one. I didn’t need more than a drop of thinner to improve the flow and I lost none of the detail, even on very tiny photoetched parts like the radars and depth charge racks on this 1/700 Fletcher. I wish I’d switched to this ages ago and all my models going forward will be primed this way—no more rattlecans for me!

I airbrush my models with this primer before laying down my primary colors. I get good coverage and details remain crisp. I use about 10-15 drops (not thinned) at a time in my gravity feed airbrush and don't have any issues with clogging. Good stuff!

EDIT: I must have gotten a bad batch the first time, I tried this primer again and had a much better experience. This time it sprays smooth, doesn’t clog my airbrush, and does a nice job self-leveling. So I’m updating this review. ORIGINAL REVIEW: Was very disappointed with this primer. I followed the instructions, spraying it unthinned at about 25-30 psi. I ended up with a very rough, powdery finish (not self-leveling at all), and the airbrush clogged and splattered large chunks. Cleaning the airbrush was very difficult and time consuming. I tried thinning it with a little water, and that helped some, but there were still the large chunks coming out of the airbrush, and the finish was very inconsistent— some areas were smooth but others were rough like sandpaper. Fortunately, this primer sanded very nicely, and it’s very tough when dry, so I at least was able to salvage the part. I’ve read lots of people rave about this product, so maybe I got a bad bottle, but I’m going back to my Tamiya white primer.

This is good for smaller projects. They say use it right out of the bottle, but it was a little thick and heavy for my taste. After adding a few drops H2O I got some nice results, great for fine details. It’s a little pricey, but also comes in colors, water cleanup and no odor. I would buy this again and save the Krylon for larger projects.

Excellent primer. Drys fast, and drys smooth. I run it through a Iwata neo cn with out to much issue. I do need to stop and clean if I do a large batch, but for doing a couple of minis at a time, no major issues. I am looking to get a .5m brush and I would expect less issues.

This is probably a fine product for those stuck in the Stone Age who don’t own an airbrush...if you enjoy slogging your way through primering minis with a brush or who are foul disposable consumers with a legacy of hundreds of aerosol cans littering the landscape! In miniatures if you aren’t a rank amateur, you absolutely own an airbrush, if for no other reason than to efficiently primer minis AND keep from polluting our environment with noxious and toxic aerosol propellants. Primering \ armies costs pennies with an airbrush vs expensive disposable aerosol cans which fill up landfills. That being said Stynylrez should be avoided for use in airbrushes, especially quality airbrushes like a Harder and Steenbeck. This stuff dries almost instantaneously. Even when cleaning the airbrush obsessively with Airbrush cleaning solutions (Vallejo, Wicked Colors etc.) or even the ubiquitous hobbyist standard homebrew (1/3 Isopropyl Alcohol, 1/3 distilled water, and 1/3 blue windshield washing fluid) and doing so obsessively EVERY single mini primed...this stuff will absolutely cover and ruin any airbrush. Think concrete. It resembles no acrylic you’ve ever used. Will trash your airbrush, seals, needle, nozzle tip etc. NOT for use with airbrushes!!!!! Then again if you source a cheapo airbrush from Harbor Freight dedicated to applying just Stylynrez...it does work well. However, make sure you can source and buy replacement seals for that model brush. You're going to need them. Any product that requires you to use solvents and noxious and toxic thinners isn't healthy for the hobbyist and isn't appropriate for the hobby.
