I read the instructions on the can and it said to let it sit for at least 8 hours. I stained it last night and when I checked this morning it was looking great. But I just checked now and it appears that there are a bunch of small dark spots that have appeared. The only thing that I can think that would have caused it is that I left it in my hot garage all day.
Is there anyway to get rid of these? How can I prevent this in the future?
