I you read the cfx paintwork forum they prefer the blue, say it brings out the colour.....
I've got some 99.5%proff IPA coming soon will try that and let u know. The alcohol not only thins but it also dry's alot quicker than either neat or watered down.
Im only a novice at this myself , but have read a hell of a lot about it.
But as they say its not the equipment its the artist that makes the body shell, and im no artist just fancied a dabble at it after playing with rattle cans. This gives a bit more variety and hey if im no good can at lest use it to go back to 1-2 colour, colour schemes.....
Just without the fumes which is a bonus in anybodies book.
