GMC and Aluminum Rims

[richard zodrow]

I just had someone looking at my 76 Palm Beach and I mentioned to them
that I was going to be getting rid of my old chrome rims and upgrading
to Alcoa Aluminum rims. They told me not to do it because they have
heard that a lot of people have had problems keeping a good seal once
the rims get a little corrosion from age. Any truth to this??? I have
had the old rims on for 20 years with no problems with air leaks. (But I
can't keep the rust from attacking the finish) What type of maintenance
is needed with the Alcoa's??

Thanks

Richard,
There is no data to back this up that I am aware of. The Alcoa is the
hot tip for the GMC, been used on GMC's for a long time with no problems
with corrosion. Our coaches typically are not used during salt season
or are already in warm areas of the country. I polish mine 2 or 3 time
a year to keep them shining.
