Funny man … My ‘new’ pin nailer hasn’t been used in 2 years!
Just in case, I bought a new compressor! Oh yeah, a shot of Sea Foam and the pins fired clean.
First contest hint: Sea Foam Deep Creep; a Multi-use penetrating lubricant. I don’t have a moisture trap on my thimble tank compressor, but a shot of sea foam lubes and protects. I shoot it into the air way of the tool. I spray the moving parts too. Comes in an aerosol can with a straw for pin point application. If that’s not enough it sez it won’t let guns freeze up in cold weather.(https://www.largescalecentral.com/externals/tinymce/plugins/emoticons/img/smiley-wink.gif)
I find it in Auto Parts stores.
