Comparing prices for both on Amazon, seems the Quick product is just a bit more expensive...
Unless they are selling it at half-price I would NOT buy at Camping World... anything.
Have you looked at all the documentation and installation tips on the Eternabond website?
I have used Eternabond and for nearly four years now swear by my Eternabond installation on my roof... I am very happy with it.
