This frame piece is designed to fit on a regular truck frame to simulate the type many log trucks use. I'm only offering this in the 'white' material, which will have the consistency of a sugar cube surface. This is easily corrected with cleaning, sanding and use a good SANDABLE auto body primer for the initial 'working coat'. Be sure and follow me as a designer in order to see any new releases, and contact me via email at modelmechanic@gmail.com if you have a question or problem.
