I use 505 in the red can LOVE IT! Doesn'yt gum up needles or hoops. Also can reposition designs several times and still sticks. Suzanne
I've never seen anything other than a red can, which I use. So I can't compare.
I use 505, but in a blue can...suggest you check their website and see if they post anything. I could be a regional thing, or just a packaging change.
I have never seen the red can. I would not use anything but 505 adhesive but I have no idea if they are the same, perhaps they have just changed the packaging.
I use the 505 all the time but cannot compare to the yellow can. The 505 is a very good product and I like it.
Hope this helps
