NO RECOATING! MEK is a "hot" solvent, and if you put it on previous paint, it will lift it!
If you are trying to "speed up" drying, use cigarette lighter fluid instead of paint thinner. You won't get much flow out, but it won't harm the paint.

I have to agree with Si,...MEK is asking for problems if you mix it with one shot,....Adding the hardener will speed up the cure time with one shot as will a hotter thinner but not as hot as MEK,....You don't say how you intend to use it and on what,so there can be a great number of variables to consider,....the primer,...the substrate,...any previous finishes,...all of these can be a potential factor that may result in a bad reaction,...after saying all that I would assume that MEK will be harsh on the medium(varnish or compound used to suspend color in the paint formula) and affect adhesion and longevity,...

I was thinking of using it in paints sprayed on the vinyl for fades in place of the high temp reducer. I wanted it to dry quick and get the bite if possible.

I use Japan drier to speed up drying. I also use a product made by kleen strip called Bulldog, to promote adhesion, its available through the auto bdy indusrty and they use it to paint all the flexable plastic pieces of cars these days

If you intend to use mek and you are set up with proper masks and protection from the hazardous chemicals to spray, try vinyl ink. It will dry faster,usually within an hour, and actually become part of the vinyl, if the vinyl is prepped properly. You can buy it in almost all the same colors if not more form most major sign and silk screen suppliers.

I don't get it. If you thin the 1-Shot for spraying, then wouldn't it lose its gloss somewhat? Aren't the proven ways using inks for fades good enough for that, or maybe I'm just stuck in my ways!

Chemists have already done the work for you and made vinyl ink!
You just can't beat using a product that's developed specifically for the task at hand, and One Shot is NOT that product.
The labor you save from having to scuff, clean, and prep the vinyl is more than worth having the ink in stock. Just wipe the vinyl down with some denatured alcohol and it's ready to be sprayed, no scuff no fuss. The ink will do the rest of the work.
The inks dry glossy, they literally melt into the vinyl and there's just no chance of a failure happening with this stuff. Not to mention the fades are smooth as silk.
$17 gets you a quart of ink which can be thinned for spraying to yield one gallon of sprayable ink.
Or call up a local screenprinter and see if they'll sell ya some small amounts of ink if you bring the jars. 3 or 4 ounces of ink goes a pretty long way (yields 9-12 ounces of sprayable material).

I gotta agree with Mike on the vinyl ink. It also has a great shelf life. I've got quarts that are close to twenty years old. IT DOES STINK, however. Del Badry told me about an automotive paint product for dashboards that supposedly works great and doesn't smell.

George..or anyone else interested... the product Del is talking about is made by SEM...classified as a vinyl dye,comes in either solvent based or waterbased. Designed to become part of the vinyl/leather interior.You can buy premixed colors of the solvent based line in spray cans or the waterbased can be mixed in certain colors in qt size qty's,it works fairly well although despite what they tell you the number of mixing colors is limited so you arent gonna be able to mix a 5000 color spectrum and match a ton of PMS colors etc,but you can get it in gloss,semi gloss or flat. Most jobbers should carry one form or the other.

I have sprayed blends on vinyl using 1-shot mixed with about 20-30% Frog Juice or 1-shot speeed dry uv clear. I believe that those products contain MEK. They bite well into vinyl.

Here is a mild tip as I speak from some trial and error issues. Something I did learn from paintinting the front ends of stock car (Racer's) that are made from a styrene / poly type material. You can use XIM 400 clear, to coat a surface which needs to be painted with a one shot color that will stay on that surface through hell and high water. No mixing of high temp reducers needed at all.

I've always thought that "Methyl Ethyl Ketone" sounded like some sort of chemical warfare agent, anyways.
What do the folks at 1-SHOT have to say on this subject? Don't they have an additive in their product line that would do the job?

the 1-shot hardner/activator will speed your drying time. the 1-shot/Chromatic Vinyl Primer (available in flat or glossy) is probably their solution to getting the paint to stick. if you go that route (prime and then activator in the paint) you can spray, brush and roll. you'll be able to stock one line of materials. the primers dry superfast (15 minutes for me) and the activated paint will dry and cure in about an hour. you'll have a "system" that can work in a variety of situations.
all that said, if you're just spraying fades, go with the vinyl ink and get a good respirator (NOT a dust mask)

i don't have the MSDS forms handy, but the "quick refernce" and the website make no mention about the 1-shot vinyl primer being only for indoor use. i've always used the Ti-Coat vinyl primer (made under the Chromatic name, which is owned by the same company as 1-shot) because it is available in a gloss finish. the Ti-Coat is "suitable for fexible faces, awning, banners and self-adhesive vinyls"... so that sounds like "exterior" to me. i've only been using it two years, but i haven't had any failures.

According to Tom Yates, Technical director at 1-Shot, Chromatic Acrylic Ticoat or 1-Shot 5005 White Acrylic Bonding Primer, are suitable for exterior applications. 1-Shot 5004 Vinyl Primer is intended for interior use only.
