I was in my Local Michael’s the other day and I saw some Krylon “Clear Matte Finish.” I thought it might be a cheaper alternative to Tesor’s Dulcote. However when I read the label, it said it contained acetone. I assumed the stuff wasn’t safe for plactic models and put it back. Do any of you guys know if you can use this stuff on plastic models?
I have used it with no problems. Your experience may not be the same. I bought it at Lowes.
I’ve used it on plastic models from N Scale to G Scale with no problems. Just mask off any clear plastic as it’ll permanently fog it.
Just test it on something first. I once got a can of it, and everything it was sprayed onto turned a milky white, including the inside of my garbage can where the rest of it got deposited.

I bought a can after reading here about other modeler’s searches for a more economical quantity of a matte spray cover than you get in a small can of DullCote. I have used it on several models, to cover the following: a new paint job, tone down a gloss coat after decals are applied and for general overcoating on various flat colors, to “secure” the paint. I have no complaints, thus far. Cedarwoodron
A good practice is to spray in thin coats.
Have used the Krylon Matte for years.
I too, wanted a cheaper alternative to Dullcote.
I did a test a couple of weeks ago to compare it to Dullcote and found that while it does work ok , it does not result in as flat a finish as Dullcote.

It works well BUT it will wear off if you handle the models a lot.
I use it also and put three coats on my new back drop (New Backdrop thread). I also use it for final finish over decals on models. I always test first on anything I haven’t used it on before. It is a good and reliable product for many of our uses. Doug
I use Plaid brand Clear Acrylic Sealer, which is available at most Wal-mart and similar stores in the crafts section. They have a matte finish as well as gloss.
With the Matte Finish be sure to mask any clear plastic on a model before spraying. Otherwise the clear plastic will fog up and you’ll probably never get it off.
Floquil has a product called “barrier” and it works as just that-a barrier. It works well. Krylon should be OK, as long as you don’t glom it on like there’s no tomorrow. Acetone, i believe, contains methyl ethyl ketone, which is pretty bad stuff. If you breathe it for a prolonged period of time, it will fry your brain out really good. Some of this stuff is pretty noxious and harmful, so do read the instructions BEFORE using.
Rich.
Acetone and methyl ethyl ketone are closely related but different chemically. But you are correct that too much of either is bad for you (especially your liver). I hope that everyone reads the directions and cautions but there is also human nature to consider.

Exactly why I use it outside. Same for enamel paints as the fumes give me respiratory fits.
I hve used the Krylon Matte Finish and Krylon Crystal Clear Flat both bought at Walley World. The only time I have got clouding is when I spray in high heat or humidity and a respray in better conditions takes care of it.
You’ew right,Joe, they re related. Acetonre is diethyl keytone a nd, of course MEK is methyl ethyl keytone. Not to get too technical in organic chemistry, but its the Keytone group within each of these compounds that make them solvents - - both very volatile and, yes, be careful and have plenty of ventilation. With any of these compounds I work with them outside
