I just recieved a bottle of MM "interior green", eventhough the bottle seems to be full, the paint is thick as clay, my question is that how much water should I add so that it wouldn't get to wet and looses its color.

Do you have the acrylic, or the enamel?

I usually don't add anything to the actual bottle, this does sound a bit different. I would go ahead and add a couple of drops in and mix. If it's still thick, add a couple more, repeat that until you get a nice consitancy. I would check it often over the next few days to make sure it doesn't thicken up again. If it does add abit more.

No you can not thin enamels with water. You must use the proper thinner. I use straight from the can low odor mineral spirits. I know that the major hobby paint brands make their own thinner, but I am pretty sure it is the same stufff and I have never noticed much difference in it, other than the price. You can buy it in gallon cans for a fraction of what a pint of testors will cost you. (Being in the prop business, I do alot of painting and use alot of thinner)

that bottle i have is enamel, so which thinner would I need? I don't wanna spend to much if I know i can spend much less.

Well, if it's enamels, you do not thin with water....
You can get a pint of mineral spirits at a hardwear store for about the same price as a small bottle of model masters thinner.
As for thinning the whole bottle.... I've never had to do that. Usually I just thin what I need using a small metal artist water color pallet, if I'm brush painting. For airbrushing I just thin it in the airbrush cup.

Yes, what GOM said. Thin the amount of paint that you need at the moment. Much easier than trying to thin the whole bottle.

Just received it and it's that thick? Sounds like spoiled paint to me. Can you bring it back to the store where you bought it? You may not be able to salvage that.

nah, I got them for almost free, so I'm better off just throwing it out if I can't safe it.


If I were to get acrylic paint instead of enamel, it would have made my life easier?, without having to use thinner and all.

Fuhrer, sorry, but I'm an oil and enamel user, so can't help in the acrylic area. But we do have many fine modellers who use nothing but acrylics, who would be able to answer all your questions on acrylics.

so, could you tell me why you perfer oil or enamel? this way at least I could get a better understanding of what im using...

Simple why I prefer them.... when I started modelling, all we had was enamels, and oils. I persoanlly have tried acrylics, but still prefer using what I learned on. With enamels, I can mix a little oil colors to the base coat, and extend the drying time for my dry-brushing. Either lightening them, or darkening the base color accordingly, depending on what I want to portray in the finished piece.
I'm sure there are others who do the same things in acrylics, I simply prefer enamels and oils.
Kind of like why does one artist prefer charcoal, and another prefers pencils..... both make pretty pictures..... it's simply what one feels more comfortable using.
