Hi James I've never had to thin rattle can paint for use in my airbrush but it depends on needle size I normally use a 0.4mm

Should be just be careful how you transfer it I normally use a straw to spray it into a clean empty ain't jar then give it a good stir before I put into my airbrush.
James do you use a compressor because canned air propellant can react with the propellant in the rattle can and cause the paint to Bloom

Decanting a rattle can is easy as long as it's done carefully. A cloth or something similar over the join between the straw & the valve helps prevent unwanted stains on the carpet etc :smiling3:

However, the most important consideration is to leave the decanted paint for a good few hours, so that the propellant can bubble off. If you don't... Captain Cockup awaits!

I am not sure why you would need to do this given the wide range of paints available now ready to be used immediately from an airbrush. Decanting seems a messy business to me best avoided!!!

Whenever I've decanted spray paint it's always required thinning a little. That said, I always go by what the paint looks like in the jar. I try to get all my paint to be the consistency of milk,this is of course a rough guide but is surprisingly effective. You should see this consistency in the way the liquid runs from the container sides.
Hope this helps

I think Barry that sometimes the colour you want, if you are doing a car, is easier to get your hands on in a car spares shop than trying to find it "airbrush ready"
And as well both know an airbrush does give a bit more control than a rattle can...

Re decanting. See if the spray top from an old WD40 tin fits the paint can. They have a top that can hold a straw. Remember to leave the decanted paint open to de gas.

I use some of them and yes they are very good. I normally use a 0.4 needle and I don't need to thin them.

Why do you have to leave it to de-gas? Doesn't the dissolved gas disperse when it leaves the nozzle? After all, it doesn't bubble if you spray it straight onto a car.

Forgive my ignorance, I've never tried decanting the paint into an airbrush.
