How many have ruined the finish on your bow with bug spray? What kind of finish and spray?
I've never ruined the finish as I've been very careful in the days when I still used bug juice.
I use a Thermacell now so it's a non issue and works better than bug dope in my opinion. "Off" makes a little clip on unit that seems to work well also.
As Charlie said Thermacell is the way to go,best product next to Sawyers for tic's.
It'll eat polyurethane I know that much. Also, plastic faces on watches are a problem.
