Viscosity cup

Ok this might seem a tad crazy but can any of my fellow Canadian woodworkers tell me what store i will find i can buy a viscosity cup at.

Seems to me the little parts like filter and viscosity cups etc for paint spraying are hard to come by. I even tried a specialist spray equipment supplier who actually shares premises with a sherwin williams store. You would think they would have these. I guess the pros dont need them. They know what they doing.

Also paint filters, scarce as hens teeth.

I've got one but I'm not sure where I got it.

Says 'GUNBEST' on it. I could have sworn I picked it up at Harbor Freight, but I can't find a model number on in.

Found a thread online where someone references a product number '47399' for it though.

I do know I picked up a bunch of paint filters at a local auto paint supply shop.

Seems like you could make your own viscosity gauge just by drilling a hole in a little metal measuring cup though... That's about all this is.

Thanks Brent. I will look around for auto spray guys.

Hi Rob,
Didn't know if you were aware of this when choosing a viscosity cup but I found this site very helpful.
Different finish mfg's use one of the listed formats for determining viscosity.

you also may consider just mail ordering one from one of the online supply houses.
