Thank you everyone for your help!!!
When I saw the videos on U-Tube with modelers using Vallejo paints I was very interested as it looked like I wouldn't need to have an exhaust booth and they wouldn't smell up the house.
It is winter here and very cold and the paints I DO have( Compucolor-precision-and Humbrol) although really great paints need chemical solvents and I usually would spray outside.
BUT with These Vallejo's I could use them right out of the bottle something I like because it cuts down on mixing and preparation time and I can keep my son's attention PLUS it doesn't look so intimidating to him to use an AirBrush.
I also like what you all said that they brush on well too!!!
Thank you ALL sop much for the information and help
