Respray session

I would leave it at least 48 hours minimum before you do your next set of coats, If not you will get crinkles from the next layer of paint drying at different rate to previous. Don't say I didn't warn you.

Will do! Anyone got any ideas where I can get decent spray cans that don't cost the earth?

I've got this portable oil radiator thing, would heating the garage help the paint cure and improve the finish?
