Please note that these engine covers are made of impact and abrasion resistant materials and may appear to have an inconsistent finish and overall look. The priority and focus of these covers is to provide the utmost protective function and so the insides may appear rough, the outsides may have fine marks or similar and the bolt spacers may appear roughed in. This is the nature of the material and the manufacturing process and in no way do any of these subjective blemishes affect the covers’ ability to protect your engine cases from abrasion and minor impacts.
