Hi Quinten,
I too use spray cans often. I have the basic Humbrol airbrush here. I use this for mixed colours, but when a standard shade is required I use the can.
Don't do lots of small quick squirts with the can as this will cause an uneven blobby effect and can cause runs if the blobs are too concentrated.
Also try not to rush in a little flurry of movement at the end of the stroke.
Spray steady to an invisible mark say an inch or two off the area being painted....press and release the paint button before the model and after the pass has gone past the model.
Always build up the colour in a few light coats.
And as Chuck mentioned, keep the can a good distance away from the model. Too close will result in heavy thick and runny coats.
Hope it helps.
Cheers
Peter
