Anybody gone down the powder coating route, particulary for the Swinging arm around the drive hub area. ? My GT 1300 is a minter but I am having the stands powder coated as they are a smigeon flaky. I have had the radiator cleaned out, crap in bottom ish five inches, no corrosion at all but if left in and salt stuck in there oh my goodness it would be a mess as others have described on here. I took out the original BM rad protector and replaced by a Wunderlech upgrade. I can see it stopping more crap getting in but fail to see the concern this design will cause overheating. I would be doubtful if the airflow is any different between the stock and the upgrade but would not be surprised if the airflows better through the upgrade, the design and construction seems to lend itself more to free flow of air but a better crap catcher. More like a high class culinder.
