When your locks get hard to work try puting powdered graphite in the locks.

Just a couple of squeezes and work the lock a couple of times.

At less than $3.00 a bottle, that's a cheap investment!

Using WD-40 will draw dirt like a magnet.                                                    After a trip I will put WD-40 on the                                                             stabilizers and work them up and down                                                           a couple of times.
