I just got a bottle last week to treat an old frame I just bought.
My can came with pretty good instructions attached with a rubber band.
If your bottle didn't have these I can scan it and e-mail it to you if you'd like.
Send me a PM if you need them.
However, looking at the instructions sounds like you don't need to worry. A little WD-40 can be used to wipe the excess off if it gets where you don't want it.
