Think they are mostly water based these days, so presumably a drop of water?  :-\

I'd experiment on some test cards before painting the car tho...

Thanks, Tig.....but adding water makes it go 'clumpy' and even thicker.

Hard to find a definitive answer.

It depends.


A small quantity that has or is intended to be applied with a brush is going to be traditional solvent based paint. You'll thin that with cellulose thinners, if necessary. Americans call this 'lacquer'


If it's an aerosol, it's probably acrylic, and you're not going to thin it. This is the 'urethane' or 'enamel' mentioned in US media.


You can get aerosols filled with 2-pack paint; these will need the integral activator cylinder(like the 'draught' beer cans) pierced, the contents mixed and then applied.


If you bought it from a paint mixer, they'll have supplied what you asked for; cellulose, acrylic, 2k, water based. You don't use 'ordinary' water as a thinner for that.

Twenty notes for 12ml of touch up paint and 12ml of touch up 'clear coat'.

Out of interest, why do you feel it needs thinning?  ???

Surely it's formulated to be applied as is?  :-\

It's simply too thick and obvious to the eye when applied straight from the brush ( also it appears too dark). Even using a smaller brush it is still not good enough.

It's not that big a deal so I'm not going to get all OCD about it. I think I can improve it though. :y

I'll be happy enough with close to perfect rather than unobtainable perfection.

Assuming that it’s for your stone chip, get a cocktail stick, chew the end to feather it out slightly, dip it in the touch up paint and touch a fine droplet in the chip. Don’t overdo it the first time as it will sit proud like a blob, like what happens with the touch up brush. Repeat a couple of times, letting each coat fully dry. When you’re happy that it’s slightly under the correct level, do the same with the clear coat. Allow it to fully harden and polish the spot to best disguise it. Don’t polish it too soon as you’ll polish it back out.  ::)  If uncertain, don’t polish it at all. It won’t ever be invisible but it won’t be so obvious. Patience is the key to this.  :y

 Potentialy you may get a small amount of cellulose thinner from a good model shop that has paint for airbrushes
