i just clean the booster surface, sandpaper it, brush on rust converter if i have any, then paint it with my choice of color. and as i have no artistic objective, i just use red lead paint.

the booster can last years, before rust eats thru the metal. but once it does, you will rue the day you decided not to fix it earlier.
i'll do it next week.. what you meant by "brush on rust converter if I have any", anong rust converter?
