lookin for some advice. im painting a few things up and im wondering if i wetsand, do i need to wash the area over again with a brush and some soap to remove the residue and particles??. i am having probs with the paint sticking, and i would rather not primer if possible

 

Are you painting plastic or metal?

 

metal

 

When ever I spray paint metal I use barake and parts cleaner 1st to clean it. It does a great job and dries immedately on contact. The paint sticks and leaves no "fish eyes."

 

any other tricks?
the prob is the paint is coming off when i wipe the piece with my hand....

 

you wanna use wetsand then primer then paint
do at least 2 coats of primer then sand down a little dry sandpaper whipe clean then apply paint at least 3 coats
any other help u may need email me: siderazeref9@aol.com

 

what kind of metal?

 

its not sticking because maybe the surface is too smooth, hit it with some rough sand paper and you wana get it nice and rough, then hit it with a base coat so it sticks. I wouldnt use any chemicals on the metal before hand if the surface area is clean, maybe some soap at first to remove any grease, but i wouldnt use anything with too many chemicals in it, some contain oils that will repel the paint.

 

the brake parts cleaner is a good idea, definetly use that method...

 

when you paint metal you MUST primer the surface, otherwise the paint will not stick as you have discovered.
