I know shellacking handle bar tape has been discussed before under the Mixte thread, but I didn't run across my specific question anywhere else.

So I applied 2 coats of amber shellac to my cork bar tape. I loved how it was looking, going from clown nose red to a deeper almost burgundy.

Problem is, I applied my final coat last night around 8:00pm to finish it off. My roommates and I don't have the air-conditioning on, so it was about 87 degrees in the apartment. Thinking it'd probably be better for the shellac to be somewhere cooler I moved it out onto the porch and then left it out there overnight (without checking to see that it was supposed to rain). When I went to grab my bike this morning my bar tape had an awful white-ish mottling all over. Talk about disappointing...

Anyone have any ideas about what happened?

Shellac is supposed to be waterproof. Did this mottling occur from getting wet hours after I applied it, or did my shellac go bad sitting inside in 85+ degree air (in a closed container)? I just bought the can recently.

Also, I've heard you can take it off with denatured alcohol. Would it be better to buy some and try the process again, or should I just go get some new tape?

Thanks in advance.
