Question : Does this product attract dirt?
Answer : Once sprayed, it leaves a light coating of PTFE (Teflon) behind, which is dry, so no dirt trapping tendencies.
Question : Can this be used on scrapbooking metal punches? Would it leave a residue on the paper underneath that is being punched through?
Answer : Since the lubricant left behind is dry and somewhat white in color, there should not be a problem for this purpose. The amounts transferred to paper should be extremely low.
Question : Can this be used on treadmill walking belts?
Answer : Treadmill belts have a 'nubby' texture on the topside, to prevent slipping, so this lubricant would make falls far more likely. If used on the underside of the belt, it would lead to slippage on the drive rollers, not a good thing. I doubt manufacturers advise any lubrication or coating of their belts, for safety reasons.
Question : Are there any rust inhibitors in this to fight corrosion?
Answer : I don't have the can available to check the contents/composition however I remember when I bought it it did state that this product prevents corrosion but not specifically rust. However since corrosion is simply a chemical reaction or oxidation process I have to assume that would include rusting. Sorry I can't be more helpful.
Question : Is this plastic safe? specifically pbt?
Answer : PBT is a very solvent resistant plastic, so the carrier solvent in the Super Lube spray is heptane, an aliphatic hydrocarbon unlikely to damage such plastics.
Question : Is it a clear lube?
Answer : When sprayed on it is clear but turns white when it dries. Melts certain plastics like auto door handles. Beware.
Question : Is this good for a 3D printer?
Answer : It will depend what part of the 3-D printer you're lubing, gears, rails maybe but I'd be very careful with an aerosol spray lubing something is delicate and complex is a 3-D printer. Aerosol lubes can go where you don't want them to go. I'd consider using the small Super Lube liquid lube, you can have more control and be more precise with the application.
Question : What's the difference between this and Super Lube 31110? My application is lubricating powered sun roof without melting rubber or silicone gaskets
Answer : Both rely on Teflon (PTFE) for their dry lubricating power, but they probably have different solvents carrying that lubricant. Hence, the 31110 'claims' to be safe on rubber or plastics, while the other variety does not. Do keep in mind that like all PTFE sprays, you may leave a visible white coating on the sprayed areas. I'd be sure to test the lubricant on a hidden area to see if any harm (softening) occurs. For something like sunroof tracks, you can also use a light coating of silicone grease, which should not harm rubber weather seals and will probably last longer!
Question : I've lost my straw extender, any idea what size is it to order a new one?
Answer : Since my straw is no longer with the can, I guess I have misplaced it. But I see you can buy 50 '6-inch Aerosol Spray Can Red Plastic Straws/Tip Extension Tubes for Automotive Lubricant' described as being '.085 (2.16 mm) Outside Diameter' ($10.99). (I found this in 'More Items to Explore' shown after the description of the Super Lube 11016 Aerosol Dri-Film.
