Hi guys, I have Tamiya spray paint PS-38 and PS-42. I know they are not lacquers but what are they and what are the rules for using them? Thanks.
Not sure what kind of paint it is, some sites list it as lacquers while others do not. Now according to Tamiya it says about this paint “These spray paints were developed especially for decorating transparent polycarbonate bodies used in R/C car modeling. Each can contains 100ml of paint, which is the appropriate amount for finishing the model. Paint the body from the inside, keeping the can about 30cm from the surface. After curing apply another coat as necessary. These paints are impervious to oil and fuels, so they can be safely used on gas-powered R/C bodies. Note: Never use these paints on plastic models.”
So if you are going to try it, may want to take either a piece you don’t need or part of the runner to see if there will be any negative interaction with the plastic.
I did. I used PS-38 over Plate Mail Metal coloured primer from ‘The Army Painter’ on my Blue Destiny Unit One without problem. I’m more curious about other people’s experiences using Tamiya clear polycarbonate spray paint on their model kits.
I have never used Tamiya’s clear spray. I normally stick with Testors and never had a problem. Id be just as interested in seeing what others have experienced. Always can shoot for a better paint job lol
The PS spray cans are mainly used for the RC cars/boats type of plastic. The TS spray line are made for model plastics. Well thats what i’ve been told anyway. I’ve used the PS spray on my gundam models and they turned out fine, tho i found it to be a bit thicker than the TS spray.
When you spray your kits does the paint comes out ( I don’t know how to say it) even or in bits and pieces, kinda spodgey? I think I made that word up lol.
🙂 i think i understand. if its coming out in bits and pieces and spodgey, then it could be a couple of reasons –
1. the can hasn’t been shaken enough (shake for at least a minute)
2. the spray can is too old (the paint is off)
3. weather conditions (very humid or very cold)
Also try to spray at a good distance from the plastic, at least 20 to 25cm (at arms length) from nozzle to plastic and move in a side to side motion.
Hope this helps 🙂
When I spray paint with it not all the area sprayed is painted, only sections and I have to build up the colour slowly. I got the paint very cheap, perhaps it is off.
When you used it what type of paint did you put it over, acrylic, lacquer, enamel etc?
i usually use an acrylic primer, then after that most other applicants (enamel etc) work fine for me, tho i do tend to use only acrylics.
it does sound like the paint is off 🙁
reasonably sure they are lacquers though not 100%. Anyways I have used a couple of the Tamiya PS line, I wasn’t paying attention when I was buying and they were the right color, anyways I’ve used them with no issues and in my case it wasn’t a top coat but rather the actual colored paint.
Really there shouldn’t be an issue despite the warning, it’s more the other way around I’d think since this paint has things in it to protect it from the things RC cars go through, in other words it has to be a sturdier paint.
Now as for the building up the paint you kinda should be doing that anyways but as for why the coat is coming out that way I’m not completely sure what the condition of your cans are but the first thing I’d do is look at the nozzle, is there something interfering with the paint’s flow.
The cans were brand new, still in the shrink wrap. I think the shop was getting rid of them to make room. When I get someone money I’ll buy some cheap HGUC’s from HLJ and try them out. Hopefully using them over enamel will work.
Thanks Steven.
well if it is lacquer you probably don’t want to use it over anything but other lacquers. Using it over enamel will make it dissolve the enamel paint.
