Slow Air Leaks on Aluminun Rims

My wife has a 1993 Accord that has perpetual slow air leaks on her
tires. One
Gas station repair shop said it is caused by a reaction from the
aluminum rims to the tires.
He has to scrape down the rims and the tire bead and then this will last
about a year.
Is there anything else that can be applied to the rims to prevent this
from reoccurring?
This is getting to be a real pain in the ass.

==================

You can tell them to use Contact Cement, but them you have to throw
the rims away when the tires go bald... :-(

Have a good weekend.

==================

 

Aluminium is porous,and needs to be sealed;there was a paragraph about this
in Pop Mechanics in their auto section last month,IIRC.
They recommended the wheels be sent to a reconditioning center to be
stripped and professionally resealed.ISTR that ordinary paint won't work
due to tire/wheel operating temperatures.

 

Our fix on our Accord 96 ex - when we replaced the OEM Michelins with
Dunlops the problem disappeared

 

I've always bought Michelins because of their long tread life, but your solution
seems to imply
that maybe there is a reaction between the Michelin tire compound and the rim.
Is it possible
for one tire manufacture to have a reaction at the bead to the rim and not
another? Guess I'll
start replacing the Michelins as they get worn down. Don't have too much to
lose at this point.

Thanks for your response.
