Just as extra insurance, yes, wait 'til after, but my problem, if this is the problem, is because it was waaaay too cold out to be doing this in a non-heated garage and I worked quickly and made a dumb mistake of probably not drying everything off as I should have. Take your time, it's not an extremely difficult process, but just like anything else, if you try to do it hurridley, problems will occur. Good luck!
