My enclosed conversion has 11 ft 1/4 round top corners on the sides and 37 years of oxidation and stains got them looking ugly. Hit with some brasso and was not at all happy so off to the store for 320, 400, 600, and 800 grit sand paper and a large can of wd40 to lube/were sand.
2 1/2 hrs later and one rail is half way done. Did a 3 ft section to test concept and it looks great but damn it's alot of work lol. Hope to post pix in a few days
