Hello Weber fans! I have a quick question. I am doing a restore on a smokey joe. The bolts for the legs to the kettle are rusted, i sprayed them to try to loosen them already (w/not much luck), should i just grind them off & replace (probably)? Also, a "cosmetic" question: The legs are slightly rusted by the bolts on the outside, steel wool as best as possible & leave original or spray paint them for a touch of color mod? Thank you in advance. Pics later after completion. Cheers! ~Jimbo
