All the Goops are pretty much the same formula.
'Amazing' and 'Craft' are thinner, while 'Wood and Furniture' is thicker.
'Automotive', Household' and 'Plumbing' are all the same thing.
'Marine', 'Sport & Outdoor', 'RV',and 'Lawn & Garden are also the same formula but UV-resistant.
'Shoe-Goo' is also the same stuff but even more flexable than the others

I use what ever is handy
