Re: Painting Trucks


It is not about stripping paint in the topic's example of painting trucks, but about altering the surface texture of the plastic to give the paint something to adhere to. Paint will NOT adhere well to shiny, slick engineering plastics (the types typically used for trucks). Grit blasting abrades the surface, creating microscopic cracks and crevices and other surface anomalies into which the paint will flow to aid adhesion.

Why is this grit blasting superior to say some kind of paint stripper? Also, what kind of paint stripper works best for taking a model all the way down to bare plastic or brass?

In addition, I recently bought a Badger "air eraser" kit (just a
bottle with some grit and a tip) and I have hooked this up with my
grit booth. I find I can safely remove small amounts of lettering
with very fine control, and I've even started using it as a
weathering tool. For example, I use it to "whiten" freight car
lettering which I have hit a little too hard with grime. In another
case I had a box car with a primer coat of "galvanized metal" color
and an overcoat of box car red. I was able to remove some of the top
layer so the galvanized color showed through. Very cool!
