I've been using J-B Weld for years. When I went to buy some new tubes today, I noticed the borg also carries J-B Kwik which claims a 4 minute set time, 4 hour cure.
My gut tells me that a longer set and cure time (J-B Weld - 15 hour cure) would be better/stronger, but I ain't no chemist.
Any thoughts on the matter? Is J-B Kwik just as good as J-B Weld when both have cured completely?
