I've just bought a re-spray kit and have it in mind to respray something previously painted with enamel paint.

I know that you can't use cellulose over enamel but what would I use to thin the new enamel I'm about to spray on? What are the thinners called?

[Job-Rated]

"Enamel paints require enamel thinner (with the exception of "acrylic enamels," which may require acrylic thinner). Enamel thinner is comprised mostly of mineral spirits, and it is sometimes referred to by that latter designation. Most all enamel thinners are compatible and pretty much any of them will work with your paint and airbrush. Enamel in spray cans is, of course, pre-thinned and ready for immediate application once shaken vigorously. Enamel thinner may usually be purchased wherever enamel paint is sold".

Thanks JR, I wonder if 'mineral spirits' includes white spirit?

I'll have to do some more browsing on the subject I think or I can see me making a right b*lls of it!

I remember from my days of making many, many Airfix/Monogram/Revel models that White Spirit is an ideal thinner for the Humbrol enamel paint I used.

O-N, you are correct in thinking that you have to be really careful as to what you use.

For the enamel paint that is available here, I would probably use naptha. But as you say, do a bit of research on this, perhaps even mail or call the paint manufacturers for advice.

Hi UJ,
I bought some enamel paint that strictly speaking is for boats and yatchs but I don't know if it is Acrylic enamel or ...er...enamel enamel!

I've brushed a bit over the existing paint finish and had no adverse reaction, I then cleaned my brush with white spirits easily enough. I suppose I might have to email the maker to be certain.

Hi O-N, if its a marine paint you have purchased, then the chances are it is an alkyd enamel. Therefore J-R was spot on when he said mineral spirits.

If you do contact the manufacturer, let us all know their answer.
