“I need a material that is recommended for engine blocks as well as a coating that is extremely chip/mar resistant. Any suggestions?”


“Since engine blocks are not exposed to sunlight, then UV resistance shouldn’t be a coating requirement. If you agree with this, then I suggest that you investigate using an epoxy powder coating. This material has excellent chemical resistance (oil, gasoline, etc.) and is very durable (chip & mar resistant). Furthermore, epoxies are very inexpensive and can provide an excellent coating in non-sunlight exposed products. If exposed to sunlight (UV light) epoxies will tend to chalk. Chalking will not adversely affect any of the previously mentioned coating properties of this material.”
