I use everyday Paint thinner on MM enamels

I was looking thru my garage, and I thought I found what I needed, cause in the big letters it said paint thinner, but when I got to looking real close, in real small letters it says 100% Mineral spirits, and doesn't that melt the plastic?

Maybe if you store the plastic in it..... I small amounts like AB'ing.... the tends to evaporate pretty fast.

Then it is OK to thin Enamels with mineral spirits to brush paint with then, cause I run out of the regular thinner.

I use odorless turp available from artist and paint stores (get the oils, brushes and palette paper while you're at it). The same stuff works naturally for my oils and the main benefit is that the whole place doesn't stink for hours.

I must admit that I've sprayed enamels only once with it as I use it for oil washes but it seemed to work.

Ive used mineral spirits for years thinning Humbrol and ive had no problems,I had problems when I used it for a wash it 'unglued' small parts.

I use standard household white-spirit for brushpainted enamels (Humbrol) and artists oils with no side effects. No probles when used as a wash provided the glue on the parts is properly dry .

I always used humbrols own enamel thinner with great success. Then i tried the cheaper alternatives of mineral spirits, balsamic turps(?), and some others that were recommended. they would work well for while but one by one, they always ended up lifting paint, ungluing items, not flowing properly, etc and I almosted destroyed work that had taken me ages. What ever i used seemed OK for one kit but destroyed the next. I thought "sod it" and went back to humbrol enamel again and have not had a problem since! Worth the extra few pence for the peace of mind!!!

Lacquer thinner cuts enamels particulary well and helps bond the paint to plastic.

I did buy a 32 oz. can of the low odor mineral spirits, and it does hardly smell at all, and the gal. can that says paint thinner in big letters you can see the letters from the other side of the room, but when you get real close it says 100% Mimeral spirits, that you almost need a magnifying glass to see, but now it smells totally different from the low odor one, way stronger, but not near as bad as real thinner I think, but I don't have any of the real thinner right now.
Now I have wrote down for thinning oils on the mineral spirits, but I was looking for something to thin the enamels to brush with until I can get to the store again, all I have is the mineral spirits, lighter fluid, alcohol, and now I'm going to look in one more of our old hiding places to see if I got anything besides old house paint in there.
My search did yield two cans one is Acrylic Enamel Reducer, and the other is Acrylic Lacquer thinner, which I don't think either is helping me at the moment is it.
So I'm still on the search.

All of my enamel paints are MM enamels, I mostly use Acrylics now....but still use an enamel now and then if I can find a specific color, or am doing a car or something.

I have used everything from lacquer automotive paint reducer, to MM airbrush thinner, to normal paint thinner. As far as airbrushing.....I would have to say that the MM airbrush thinner does work the best to thin MM enamels.....but you can use anything.
