For pretty much all my kitbashing/repainting life i've used Humbrol paints as that's all the local hobby shop stocks. However if I drive an hour north the Toyworld up there stocks Humbrol, Testors and Citadel. Now i've used Citadel before to not very much luck and don't have much desire to do so again. But I figured it was time to use some Testors as a lot of people swear by them. And I was looking at their spray paints and was thinking of trying them as a base coat and then brush on the small details. How are they as a spray paint? Do they need an undercoat first or will it bond with the plastic without any aid? Basically any recommendations/tips would be appreciated. I have no trouble brushing but I also like to try out new things.
