Does anybody know where a person can get a " mini-vac " or something to vacuum out areas like this. Do you just make an adapter for a small vac ? I would like to get as much of this stuff out as I can ,get it good and dry and do a 50 cent application of rust reformer. Maybe a shot of paint where I can get to.
Might even drill a hole or 2 to access the area and allow it to breathe better.
I modified a section of garden hose and. PvC connection onto my shop vac to clear the frame rail extensions and any other area I couldn't see directly into. Used a bottle brush attached to a straightened wire coat hanger to loosen things up.
