Best tool to remove Urethane?

[jon1996]

I put in alot of Urethane glued Windows in Heavy equip at work ans was wondering the best tool to remove the glue from the frame, I use at this moment a puddy knife that I welded a bolt on and take a hammer and hit it, and I have a dremel Multi oscillating tool I use but they are both slow
Thanks

If they are anything like car windshields, an Olfa knife with a fresh blade is the quickest. The fresh blade is key. Dull, like a putty knife, is next to worthless on urethane. Are you trying to remove all of the urethane? If so, what is the reason? Normally, urethane will bond to urethane very well, so removing all of it isn't necessary. If you are trying to get down to fresh metal, a wire wheel on a drill or angle grinder after slicing most off with the Olfa is pretty quick.

I have always removed the old Urethane before applying the new, I did not know i could glue over it, Where can one buy a olfa knife, Im off to amazon and see if they have it

Just make sure to clean the remaining urethane very well with a cleaner that leaves no residue. DO NOT prime the old urethane. The primer is for use on metal/paint, not urethane.
