Hello CSmith--One Shot works very well, but anything at all on glass remains a little delicate.. I always apply spar marine varnish on top of the One Shot extending about 1/8th. inch all around..this will hold it tight for a good while..No heavy handed scrubbing or scraping & I wouldn't advise a high pressure cleaning, although this one goes through a car wash with no problems..You can add Japan dryer to your One Shot but I rarely ever do..the Marine emblem would be very pretty so by all means don't shy away just because it's glass..I hope you don't have as much trouble getting to it as I did..I had to hang by my toes & lay on my tummy..

I guess I'm just spoiled working at the easle so much..good luck to you on this..It would be a very handsome job..Be sure to clean your glass very well with a vinegar & water mixture--you can't rely on glass cleaners..
