Nice vid. Suppose you were painting plastic pieces that come primered from the factory. What if anything would you do differently? Thanks in advance!

I would test a spot with paint thinner, if the primer came up easily I'd remove it and start with raw plastic. If the primer was good, I'd just sand it with 600, base and clear.

thats strange, i used to use soap and water initially but then i would get these bubbles like my paint was oil. ended up switching to simple green for my intitial cleaning and post sanding with water.

I've actually never used soap and water just sanding paste. I have found that if you let it air dry after getting wet and the plastic waterspots that it shows threw (more on light metallics), so always dry them right away...maybe your was just a particular type of soap?

Hi, is that a 3M Accuspray spray gun you use for base coat ? Does it work fine ?

I have one to, but i only use it for primer, as the tip is 1.8 mm, and i was thinking it was to big for base coat..

@jimmo4life *Nods*. Some soaps leave a layer so make the next cleaning job easier or create extra shine. Specially floor cleaners have this. Most dish washing soaps don't. But the last rub with alcohol base cleaner should remove any residue.
