Quoted from Arcade:
I talked to me friend that owns the body shop and he told me to get DBC grade with the reducer and that it would need to be clear coated. Are you using automotive clear coat or off the shelf at home depot clear coat? Also.. he mentioned there is a "shop grade" auto paint he won't use because it only last about 5 years on an automobile in the sun but would probably work well for this application and would cost less. Any thoughts? I know this paint is much more expensive but in the long run if you only use a little of it is it close to the cost of putting multiple coats of home grade paint like the Behr paint mentioned above?
I use either PPG OMNI or Shopline. Both paints work EXCELLENTLY for our game restorations. That said, they are on the lower end of the automotive paint spectrum as discussed. This makes them reasonably priced, yet still very good for out purposes. Your friend is probably correct in the longevity for a car, but we don't purposely keep our pinballs outside in the sun baking all day. Also, the clear - depending on which kind you use - will also aid in the UV protection. The clear I use is also PPG - in the OMNI brand it is 161.
In the end, I use automotive paint because it is harder/tougher, lasts longer, is smoother when applied, and looks much much better. I know there might be some who would disagree, and I know there are some people that do good work with latex, but if you put a latex painted cab up against a sprayed automotive painted cab, and there is no comparison. Just my .02
