interior plastic color change

Another vote for the SEM Flexible Color Coat vinyl dye. SEM also makes a good cleaner (#38343),or this is actually a good application for Bleche White. Then when you are absolutely sure everything is clean, rinsed and dried apply a light coat of 38363 Sand Free primer. For hard plastic apply another medium/wet coat and before it dries spray on a medium coat of your color. For hard plastic make sure the primer doesn't dry before the first coat of color. Soft vinyl doesn't even require any primer, just make sure it's clean and dry. I have painted a lot of vinyl and plastic with the SEM products and had excellent results and it adheres and lasts well. Wish I could say I've had good results with other product........but I can't. The good thing with the SEM products is you can have an exact match of color on hard plastic and soft vinyl.

Good luck.
