Question about satin. I want to do this on my probe but I have to do a little body work first. Ive read that the satin rustoleum rolls on just as well as it sprays from rattle cans. I was wondering if I should just spray bomb it. If I'm going to roll it i think i would have to take the entire car apart (bumpers, mirrors, fenders, etc) the only reason is because i would want to get all the little cracks and everything painted. so which method would yield the best results?



You will get a better overall effect by rolling on your satin paint.

I gave this speech previously... but it does explain the benefits of rolling on a paint compared to using a spray bomb...

When you are rolling on a paint.... it self levels. This is because you are directly rolling the paint and its carrier ( the mineral spirit ) on to the target part. You lose none of the paint in to the air during the transfer and 100% of what goes on the roller ends up on the target part.

When you are spraying with an aerosol or spray bomb, the paint particles are propelled out of the can and the particles fly through the air until they land on the car. While the paint particles are in flight... they are losing some of their adhesiveness. So some particles of the spray hit the target part with 100% of their adhesion quality intact... whereas other particles have underwent a various percentages of adhesion loss during the flight. SOOOOOOOooo.. when the particles hit the target surface they tend to build on top of each other. These paint molecules do not all land in an orderly fashion as they build up their coat of paint. There will be air gaps created between some particles AND in other instances you will have these 100% adhesion molecules landing on paint molecules that had lesser percentages of adhesion. That makes them very unstable and easily rubbed off.

Ok... so the roller paint goes on the car and it fills in all the air gaps and creates a uniform adhesion between all the paint molecules and the subsurface that is being painted. As the paint dries and the carrier ( mineral spirit evaporates ) the paint molecules fill in all the air gaps with the paint molecules and create a strong bond amongst itself while it self-levels. You cannot take your thumb or brush against the paint with your leg or sleeve and dislodge the paint once it has self leveled and cured.

Whereas the spray bomb job leaves a paint on the surface of the vehicle that on looking at it under a microscope would make you think that it looks kind of fuzzy. That fuzziness when rubbed with your thumb, pant leg or sleeve will rub off.

Satin paint jobs are a big enough pain in the butt to keep looking good and flat. The roll on method gives you that chance to keep that 'flat' look longer because of what I explained earlier.

Hope this helps
