Thinning oil based paint for spray

Ordinarily, I’d thin paint for spray using naphtha because it dries quickly, but my local paint store has apparently stopped carrying it. What are some fast drying alternatives?

I would not stray too far from the suggested thinner
listed on the instructions of the product you are using.

I second checking the can for the recommended thinner. I think that mineral spirits are the recommended for most oil-based stuff, though i have seen mentions of one of the -lynes being used for faster drying. Xylene maybe?

I need cheaper hobby

Home Depot carries it.

The directions on the can do not specify a thinner for spray (or any thinner for that matter). Is it possible that it shouldn't be thinned?

it would put us all on the same page as you if you could share
the brand name and any other information of the paint you are using.
also - what spray equipment you are using
and what projects are you spraying with paint ??

I've seen it at Tractor Supply, Family Farm and Home, Home Depot, Lowes and Ace Hardware. Auto motive supply like Auto Zone and O Reilly's will have it. I use it with the TSC enamels and their hardener. It gives a great result on tractors:

The answer to your question will only be as detailed and specific as the question is detailed and specific. Good questions also include a sketch or a photo that illustrates your issue. (:< D)

It's Sherwin Williams All Surface Enamel - Oil Base Gloss. I'm planning to spray a set of metal chairs using a Devilbiss Plus Gravity Spray gun. I have tips up to 1.8. I don't think it will spray unthinned. I'm not so concerned about getting perfect gloss, I just don't want to have to brush the nooks and crannies.

I just came from my local WalMart and they carry VM&P Naphtha.
I checked the MSDS, SDS, MDS, and other sources and could not
find a recommended thinner for that paint.
you could go out on a limb and use mineral spirits or Xylene at your
own discretion.
or ~ call the Sherwin Williams help line and get it right from the source.

Another option is Flood Penetrol which is their oil based paint additive. Not to be confused with their Floetrol which is for latex based paint. Both are available at Home Depot.

Some states have limitations, CA is one of the worst.

I heard you need a permit to possess DNA.

They stopped issuing permits to possess DNA a while back, and past permits, once expired, can no longer be renewed.


All DNA is now considered state government property, the use of which does not constitute possession, nor the right to possess.


And... there is a Use Tax due every year.

Good call on the Penetrol for most uses.

This is such a simple rule that it should be a Sticky: WRT any, and that means ANY product, if there’s a question about what you can do to or with their product, call the manufacturer for their guidance!

-> Do you mind sharing your source(s) for the above statements? I saw this same post in another thread, and would like to read the details for myself.

I searched on the web and found some information, but could not find what you said above. At the same time, I can confirm that DNA is not on the shelves in consumer stores in So Cal any more. I bought it last summer as "stove fuel", but since then even the "alcohol stove fuel" was removed from shelves.

If you bought it at S&W they should have given you a data sheet. . They always give me one but I have the S&W data book....if it says mineral spirits then only reduce enough to get it to spray....if it still struggles reduce it some more.

I'm so sorry. I was making a joke about Deoxyribonucleic acid.. the biological building blocks from which we are made.


I totally missed the possibility that another poster made mention of DNA as short hand for Denatured Alcohol. I thought he was talking about DNA... the substance that catches criminals 30 years after they thought they got away with murder.


Please ignore my earlier joke, and carry on buying alcohol. Just don't open the container until safe at home, in case you get stopped.
