Bloody Legionnaire Posted June 29, 2018 Share Posted June 29, 2018 Alright guys, I have to give it to Badger Airbrush Co. and their Stynylrez product. I've been searching for a good primer to use on both my plastics and resin kits. I've used Rust-o-leum- Painters touch primer, Tamiya Surface Primer, and Vallejo Surface Primer and wasn't really satisfied with the results. The Tamiya primer did fine but you absolutely have to paint outside or in a well ventilated area. My online searches led me to Stynylrez, and really seemed like the perfect primer, on paper.. I liked what I read and decided to try some out. I'll admit I wasn't super impressed when I first started using it. I found the primer was very fluid and as I airbrushed it on it applied very thin which gave me some doubts about how tough it was going to be. After along the primer to dry overnight, I checked the durability the next say, and sure enough.. it scratched just as easily as the vallejo. At this point I was ready to give up on the Polyurethane primers and figured they just didn't match up to the harder enamel and lacquer primers. After a few months of working at my hobby table and staring at the same bottle of Stynylrez that I'd given up on, I noticed how the primer separated from whatever other fluid they put in the stuff. It made me wonder if the primer was just formulated wrong so I poured a bit of the fluid it out, shook the bottle for a few minutes, and let it sit for a day. I retried the Stynylrez on a resin sprue and let that dry overnight. The following 2 images are from that sprue. In this image reference the scratches on the left side of the sprue. The small one closest to the bits came from rubbing firmly with a toothpick. It was the ONLY scratch I could get to show up on the resin following my best attempts to getting a scratch. I'm sure you noticed there are plenty of scratches under it.. that came from using the tip of my hobby knife... In this image reference the shine on the primer. That was all caused by my rubbing the tip of a toothpick firm across the primer. This stuff is tough! I'm pretty impressed with the results (especially on resin!). I'm not a chemistry guy at all and I don't know what chemicals they are using in their formula that caused the primer to not dry as hard initially. If you guys are looking for a good resilient primer I'd pick up a bottle and see if it fits your needs. Stynylrez primer has definitely earned my confidence!

Imren Posted June 29, 2018 Share Posted June 29, 2018 Sounds like you discovered the need or curing time for polyurethane primers. Vallejo surface primers (and the vallejo mecha primers) need just as the Stylnylrez to cure for 24-36 hrs. You can apply the primer and after drying for half an hour you'll discover that they come off easily. But after 24h you'll find that they are way more scratch resistant. Bottom line is, the vallejo primers are as good as stynylrez (I've used both of them) if you just apply them on cleaned resin/plastic or metal and allow for 1.5-2 days of curing.

Bung Posted June 29, 2018 Share Posted June 29, 2018 I use the Mig One Shot Primers which are rebranded Stynylrez and i prefer them over the Vallejo ones. Dont know why, but they are working better for me than Vallejo ones.

sarabando Posted June 29, 2018 Share Posted June 29, 2018 i love the VJ primers its all i use nowadays. Imren is 100% right though just because its touch dry doesn't mean its ready. i try to leave mine at least 24 hours before paint. When my current bottle runs out i shall try some of this though.

SickSix Posted June 29, 2018 Share Posted June 29, 2018 I have never had an issue with Vallejo primers when the pieces are properly prepared and left to dry for a day.

Semper Fortis Posted June 29, 2018 Share Posted June 29, 2018 Another vote in praise for Stynylrez! Like Bloody Legionnaire, I find it much more scratch resistant than any other primer I've used. And because I'm such a slow painter, I also notice a marked improvement in rub resistance from handling. I find their yellow is perfect for priming Imperator Fists. Just had their metallic delivered and will be trying it out soon.

I have some models that I've coated with Vallejo Primer that the paint will peel right off from even after months of it drying. I'm sure that is well past the cure time... Not to mention Vallejo is absolutely terrible on resin. Link to comment https://bolterandchainsword.com/topic/348563-stynylrez-praise/#findComment-5114939 Share on other sites More sharing options...
Ovidius Incertus Posted June 29, 2018 Share Posted June 29, 2018 Definitely agree with Bloody that Vallejo just is a no-go for resin; I have experienced way too much peeling with that combo. I recently got some Stynlrez and, although I do find it quite superior to Vallejo, I still prefer my Duplicolor sandable auto primer as "the best"...granted it has all its drawbacks of being a spray-on auto primer. My main issue with Stynlrez at this point is coverage. It takes a lot more coats to get ideal coverage (compared to Duplicolor), especially with gray, but it really doesn't clog detail and really does have the self-leveling effects that it's advertised to have. I have yet to spray Stynlrez on resin yet, so we shall see about that, but so far I've liked what I see on plastic.

Evil Eye Posted June 30, 2018 Share Posted June 30, 2018 I have to be honest, I cannot stand Vallejo primer, mainly for what it does to my airbrush. Tip dry and clogs like no tomorrow- and the white primer is completely useless. Personally I'm not looking back from Mr. Surfacer's lacquer airbrush primers + lots of Mr. Leveling Thinner- it's durable and dries (reasonably) fast, goes through the brush like a dream and the leveling thinner guarantees smooth results. Granted it's not very good for you (I forgot to wear a mask with it once and started trembling, which was very annoying as I couldn't hold my model steady) but it's the only way I prime anymore.

I should note, as much as I like the stynylrez it is not the end all be all of primers. The solvent based primers are going to be much more durable than non-solvent primers. I just like the ability to airbrush indoors and have less exposure to chemicals when I have to clean out my airbrush.
