OK, motor oil 10-30 NON DETERGENT............if you ingest it will do nothing more then what a good dose of CASTER OIL will do)))))))))))))
like it says on the can, NON-DETERGENT, which means it has no added chemical cleaners.
i have a sign kit from an older sign person, his brushes are still in the same kit i got in 1998-99. these are sitting in MOTOR OIL, and he had passed away bout 4-5 years beofre i got his kit. i can go out there and take out one of his brushes, clean it in turps and use it.
so i believe them to have been in the motor oil for at leastbout 10 years......with no problem.
sticken with the motor oil end here, most paints you use are what base???? OIL BASED PAINTS, huh? and where do you suppose they get that OIL???? its a PETROLEUM OIL!!!!!
and yes virgina, if your paint gets to thick sometimes adding a little motor oil with bring back its proper viscosity)))))) as for motor oil hurting the glue in the farrel, unless its glue made from animals, then it also is PETROLEUM BASED. and the NON-DETERGENT OIL, will not harm it.
now TRANNY FLUID, MARVEL MYSTERY OIL, and other automotive products, ALL CONTAIN DETERGENT TYPE CHEMICALS. this is what makes them work so well.
as for lard, i agree its good stuff, but just like one eye, dave drane and i have said, warm climates, is not a place for this. i dont care how tight that box is, say your out lettering a window, open your brush box, and leave it open for 10-20 min. HERE, the chances of some critter checking out its contents is way better then if your in mich/new york. and say you didnt see the critter get in there.........well next time you open the box, she had a family, and they all are good and fat..............from eating the brushes))))))))))
as for neatsfoot oil, getting 100% of this is almost impossible today. what you do get, will EVAPORATE over time. how do i know? i stored some brushes in it..........when i went to get em......THEY WAS ENCASED IN A HARD VARNISH LIKE GOB. cleaning them was a bear and i lost a couple good langnickles!!!!!
