Krylon Paint for plastic - Model Railroader Magazine
I have used Krylon paints professionally for years on plastics of ALL types, it is the ONLY rattle can spray paint that I use. The "Fusion" type are even better, though limited in colour selection. "Fusion" requires no primer at all on any plastic surface. Regular Krylon covers a little better when used with a primer, though with dark colours you can skip the primer stage. In professional model-building, a RELIABLE and SURE-FIRE paint is EXTREMELY important, you don't have time for crazing, wrinkling, lifting or slow drying of other paint brands. Don't bother with the little cans, they're not cost effective.
Make sure that the can and surface to be painted is room temperature when using, I often warm the can in a pail of WARM water for execellent results.
If you have trouble finding Krylon, check the yellow pages for industrial or automotive paint suppliers, they often carry a better selection.
