re: If the tractor is stopped, and the bucket is just falling like in float, what would be the negative?
he used the word 'slam', that to me means a very FORCEFUL action. If you watch/play hockey 'slamming someone into the walls is NOT a 'gentle' action !
As for 'sprays', all will be a one use deal. Move enough snow/ice, the 'spray' will be rubbed off. hmm, a spray paint, like the ceramic VHT ones, might work real slick.... there are spray on epoxy paints (RC hobby shops...) that might work. PREP of the bucket is 99.44% of the job...
