I got my shop air compressor from a dealer because of Amour-all.The compressors were in a clean room next to the body shop.They decided to use the room for new car prep and used car recon and detailing.All of a sudden all paint work in the body shop turned into a disaster.Between the ceiling fans ,a lot of compressor use by the body shop,and a run of vinyl roof cleanups,the compressors sucked up a lot of the stuff.They didn't skimp on curing the problem,new compressors,all new black iron lines,all new hoses,anything remotely connected to the problem got replaced.I took the compressor apart and washed everything with some kind of chemical that removes silicone.It may have been MEK,I can't remember.I sloshed 5 gallons around in the 80 gallon tank for a while.I won't have any silicone sprays in my garage now.
