Hello and happy holidays! I have a question......first of all I'm not sure if this is the appropriate forum for this one, but I don't know where else it would go so I figure this is as good of a place as any. Anyhow, I seem to be experiencing some issues with my knees and I'm fairly certain it's from being on them all the time to get to the lower part of the car. So my question is what do you guys use for your knees? Regular knee pads? Something special? Something other than knee pads? Thanks.
