Re: [DML] Custom Made Gas-Flap door

["Dave Swingle" <swingle@xxxxxxxxxxx>]

Based on the experience where SS screws are used in aluminum rivnuts, 
I'd say it's a problem. This is the combination that you often see in 
the car where you absolutely cannot get the screws out of the 
rivnuts - they "weld" together really well. The screws that hold the 
radiator shroud to the body come to mind. It's the aluminum that 
corrodes, the stainless does not appear to degrade but it sure sticks 
together well.
