Expertise

I can answer any question concerning automotive plastics repair on condition that the specific part polymer is identified. However, I can also help in the identifying process of any plastic used in automotive applications (for both body work and under-the-hood). I can't answer a question if it is based only on make or model unless full details are provided.
