Quick question. I have noticed by watching these forums that some of you use a dip tube for sealing your bows. Was wondering how you keep your urethane from getting really bad runs? If your thinning it, please do tell the proper way to mix it. I'll probably be using Helmsman spar urethane. I'm familiar with a lot of the other technics such as brushing it on, spraying it on, or just using oils to seal. Was wanting to give the dipping technique a try. Any tips are appreciated.
