I think that StickNBond is a new retail, or maybe even, private/OEM line of Eternabond products. I was at my local RV Superstore looking to price out some Eternabond and could only find StickNBond.
What's interesting is that the packaging for StickNBond uses some of the same packing information and images found on Eternabond products and their website. Take a look at this URL for example: EternaBond RoofSeal
The guy in the raincoat (left side of page) is the same image used on the StickNBond packaging.
A quick google search - it looks like the PPL Motorhomes site answers that question Eternabond (now Sticknbond) RV Leak Repair for sale - PPL Motor Homes
: "Eternabond products are now packaged in smaller quantities under the name Sticknbond. Produced with the same Microsealant Technology, these products are an easy-to-use, one step, peel and stick process."
I haven't yet "done the math" to see which product is a better deal. The RV Superstore I go to here has a 4x37 roll of StickNBond for $79 ... but is the StickNBond product equivalent to Eternabond RoofSeal, EternaBond RoofSeal PLUS .. or ???
