Accidentally mixed slow and medium hardener. Any ideas?
I used up the original jug of slow hardener and had to order more. CLC was out of the slow and sent me the medium hardener. As I started to run out of the small bottle of medium I wasnt thinking and combined the 2 jugs and put a coat on the hull bottom. Any ideas if this will be a disaster?

In fact, that's the only way to make medium hardener for Silvertip - mix equal parts fast & slow.

Gosh, I do that all the time ON PURPOSE. With the MAS brand, you can mix hardeners willy-nilly for a custom cure time. As long as the ratio of resin to hardener (two-to-one) never waivers, you're good with any blend of hardener.

not a problem, assuming that it is all the same *brand.* The only thing that changes is cure time -- In fact, one can intentionally mix two different speed hardeners (e.g. fast/slow) to change the cure time.
Here's the FAQ on the Mas epoxy website that discusses that:
