Stewart single component white primer
The single component primer with Ekopoly grey 2k finish has been very scratch resistant.
However, as I have warned many times, you must completely cover the primer with 2K material . ALL exposed edges or wicking paths TO the primer for solvents or mogas WILL soften and blister the finish coat.
