Must be the new generation bodyshops nowadays,
but the only fillers applied to a body was on bare
metal only...At GM every product on the market We
had and used daily, plus using experimental products, materials that never was introduced to the market because of being so toxic...I am sure that the 2K primers would be waterproof, being a urethane
based primer...The flat looking black cars, they
painted with flattening compound in the paint that
kills the gloss...Was popular on street rods...
