This stuff is a variation of what is supplied with a new ender 3 pro.
Dark grey, rough satin finish, if PETG is going to stick, its stuck forever although you can at just the right angle, get under it with a freshly sharpened, on one side only, putty knife and peel it off, but a knife that sharp shaves the plastic too, so you wind up with a lot of PETG, under .01mm thick, stuck to it forever. > > > An occasional wipe with an alcohol-soaked rag helps on the > > > occasions when adhesion isn't working. Didn't work here, but obviously I don't have the same material you do. Alky doesn't seem to affect this almost black stuff one way or the other. I'll look around now that I know what color it is. Real thin like HV kaptan, or thicker? Adhesive backed? > > Paint store alky I assume, or is 91% good enough? > > Isopropanol. Also what I use for cleaning flux off of PCBs. So do I for PCB's but running low, gotta find a paint store with gallons, getting hard to find now. Ditto acetone cuz everytime you carry a gallon, or even quarts to the register they think you're makeing meth. Acetone is faster, but like Freon TF, leaves to much crap behind as it dries. It also damages epoxy glues. I used to buy 6 gallon cases of TF until I ran out, tried the paint store alky and discovered I was only doing about 5% as much head cleaning as I was with TF. Got my attention in less than a week, it was that obvious. DVC-PRO video heads, at $3500 a copy also lasted longer, giving me the idea that TF was damaging the glues holding those very precise ferrite bits together. Never bought another gallon of TF. Went from 2500 spinning hours life to 7500+. Rated for 1000. That was something I could show in my annual budget estimate when theres 13 of them scattered around the building. :) Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
