If you have not done so already, I would still apply the tef-gel to the rivets, especially if you are going to use stainless rivets. If you are using aluminum, I would still use it to keep the rivets from reacting with the stainless snaps. Just my $.02.

There is a gel called TEF-Gel (comes in a small tube - should be available in any marine supply store). This should be applied to the threads of the snap screws when installing. This will reduce corrosion between the two dissimilar metals. You "should" remove them every year and re-apply TEF-Gel. Just hand tighten snug.

Thanks, Chris

I did receive 60 washers from Tiara (less than $10, delivered).  The only difference is that the new ones are twice the thickness.  Snaps were all riveted on to arch.  Will probably reinstall the same way.
