The Minimizer™ fender itself should never need maintenance other than the occasional wash using any all purpose cleaner. Paint is not necessary because the polyethylene material used to make the Minimizer™ fender is corrosion resistant.
Make sure that all the bolts attaching the fender to the mounting hardware are snug and not overly tight. Occasionally check the bolts holding the mounting hardware to the frame to assure they are securely tightened.
If you bend or break any of the mounting hardware replace them immediately. This will relieve any stress on the fender. If you have any questions about your Minimizer™ fenders please do no hesitate to call our customer service representatives at 800-248-3855.
Again, thank you for choosing the Minimizer™ poly fender.
