I'm a noob so please forgive the obvious questions.
I run my MERV in wet grass and need to clean it now - I washed it properly to get all the mud/grass out and now need to apply some WD40 - as per people's suggestion.
How do I apply it? Should I just spray the whole truck? I read that bearings can get damaged by WD40? Which parts should I do? should I wait for the truck try dry completely?
Please share your thoughts,
