When I took my old Town Car metal winter rims and winter tires to put on the Conti I bought this fall, I was told that the old winter rims would not fit, and that the bolt pattern on the Continental takes only alloy rims. Normally I like to have a set of cheap rims with the winter tires, so the installation is fast and cheap - plus - the alloy clear coat is not exposed to the winter salt and grime. Anyway for this time round I had to put the winter tires on the good alloys, so they wont look very good come spring. I should mention that these rims already need work, since the last owner must have driven them in winter. They already have that white "rust" on them. My question is - for those of you driving in the north where salt is used during winter...how do you keep the alloys looking new? Do you just let them go and forget about it, or have them refinished every couple of years? Or do you get a "winter" set of alloys from the wrecker, and have another set that never see the winter? Thanks.
