Question: what's the difference between this and the grey wing adapter?
ArtPrimo: The Blue Wing adapter is compatible with most hardware store paints- the Grey is for Turbo cans.

Question: Can I fit an astro cap on this adapter?
ArtPrimo: We haven't tried that specific combination, but it should work. Let us know!

Question: will this work on 24oz turbos?
ArtPrimo: For Turbos, try the Grey Uprok.

Question: UPROK Wing Adapter is placed on a female can, so that you can use Female caps with it.... Right? Not super clear to the uninitiated.
ArtPrimo: Adapters are almost always for Male Cans since most desirable caps are all male themselves; hence why you need an adapter.

Also description lists this is for MALE Rusto cans.
