If it isn't identical, it's probably not actually labeled as grey butyl - it's probably one of the similar variants that sits on the same shelf. A lot of people don't know what they are actually looking at when shopping for butyl for the first time.
Yeah, I have bought it from rv supply stores and mobile home parts manufacturers. Typically these stores have 4 to 5 different kinds of grey butyl tape on their shelves. Each good for different applications.
I personally like the kind that can stretch and has the consistency of chewed gum. Some grey butyl tape is more like a playdoh-ish consistency and doesn't stretch well.
Like he said if you get the right stuff its all the same. I buy mine for under $6 for a 30 foot roll.
I personally will never go back to curing sealants.
