Minwax Polycrylic

[Russ]

The Doctor****ADDENDUM. Use VARATHANE waterbase polyurethane instead of Minwax. It is MUCH better quality. Sorry, guys. I just learned this. The Doctor

I've been using Minwax for years on my foamies, thanks for the tip, I'll try it. Never thought of using it as a primer...nice!

[Grossman56]

both are great, I've been using Minwax PRO spar Urethane, IMHO, it gives me the glossiest finish. I also have used the Varathane version as well, I just find that the Minwax Pro is the glossiest

Great thread. I bought Minwax MATTE from walmart and I be darn if it still has a shine to it.

I did notice when it came to putting it on color reds I had to apply it heavy and then spread it out, had to keep the brush (foam) soaked


I want to try Varathane matte, know any where to get it that is not a gallon?

Will 91% alcohol break the paint? I think it will. If you are going to repaint the plane, then, it does not matter. I tried to coat my new F4U with minwax and had an awful time getting it to stick. I had to sand it down using various grits of paper before I got a finish I could live with. I think it took at least 4 coats and sanding between each coat before reached a point of acceptable finish. What help was sanding and then using the spray tape and sanding again and using a foam brush. This is the very first time I had this issue. There was oil somewhere on the finish. The plane looks really nice now and I will leave good enough alone.

BTW, Could'nt get the Spar Urethane outdoor water based at Home Depot, so ordered it from Amazon a week ago (satin, semi-gloss and gloss). Amazon just sent me a notice that UPS damaged the shipment and is returning it to Amazon and they will credit me. So I just ordered them from Zoro, should have done that to begin with. Free shipping and never had a problem with Zoro.

WRT minwax I get the satin in a spray can, apply dusty to keep the gloss down and blend everything, 2-3 light coats works best. The dusty texture helps to hide the foam and blend the decals.

Acetone will break the paint fairly quickly. 91% alcohol isn't as aggressive.

In general I wipe a model down with alcohol wipes then paint directly over the factory paint without any sanding or primer. However, certain paints will prefer light sanding to give more "bite". Vallejo's line of 2-in-1 primers works really well in my experience.

Like medical alcohol wipes?

Anyone else have the problem with the Minwax poly spraying out blobs every now and again ? I have tried shaking can for ever, heating can in hot water, leaving can in sun (Florida) and does not solve. I usually spray by starting, making the pass and stopping. Continual spraying does not work any better. Nozzle is clean. Getting nervous now when I start. If quick can wipe away these blobs but ————. Finding brushing is the safer option lately. Applies to any sheen level.

Trying using an airbrush it will give you a flatter finish.

Grossman56

Wonder why that is? I don’t have a air bush like use for detailing but I do have a hvlp gun. I bought some
of the spar utherne that people mention have better results.

[crxmanpat]

I never have good luck using the spray cans. I prefer brushing it on with a fine bristle or foam brush.

[Grossman56]

From my experience, I've found that a brush will give you a glossier finish and an Air Brush will give you a duller finish. Probably something to do with blasting it on with air, but I'm not sure, I only know that its true.

You can find this product in the US. It's used in Automotive restoration. I've used quite a few cans. It's formulated as a 2-part product in a 1-part application. No Isocyanates! I coated a Dynam P47 with it and it dried crystal clear and a really hard, UV resistant finish. It has a strong smell like bubble gum. Truth is, any product with a Skull and Crossbones symbol will really do the job! Which is to say unfortunately that "Bad Is Good !"...

Hey Grossman..Have seen you on here a ton and I know you have 2 or 3 FMS P51's. I had to buy a new fuse for my Redtail , got it all back together, and the freakin canopy will not lock down. Somewhere about the middle it feels like its pushing on something. I cut foam and cut foam then trimmed some more with no luck. The BB Doll canopy will not go on it either and the Redtail one that I am using snaps right on to the BB Doll. An ideas? The planes are set up exactly the same, receiver in the same spot et. So I know its not hitting on the RX. I cant find the issue anywhere...wondering if the fuse is screwed up but I cant find where..it's freakin brand new ! Did FMS change something you know of?

[Grossman56]

Boy, that's a tough one, the only thing I can think of to do is to paint the bottom and sides of the hatch (I gather that what you're referring to is the whole hatch and not just the canopy) push it home and see where the paint is disturbed. Other than that, I really haven't any alternative. Hope that will at least show you where its hanging up.

[thisguy65]

Grossman, what air brush do you use to spray minwax?

That's a good idea...will try it tomorrow. hahaha I figured you might have something in that head of yours to help me.
