OK the drives are striped but what do I use to fill in the pitts from corrosion sp? What will hold to aluminum and not pop out after I spend all this time making them look good?

I would paint them with a really good etching paint. Remember that alluminum corodes in about 30 min there will be a skin of corrosion on it, so you want to prep it and get it to prime ASAP. After that since your pits are probably all fine then take a finish bondo and use that to fair it out. Then sand, prime again because when you sand you will go through the primer in a lot of places then paint with a quality eurathane.

You picked a bad week to actually want boating info

try all-metal, its a bondo like product that sticks to metal very well

Thanks, It looks as if there was no primer under what ever they were done in before. The paint came off in large sheets.

What about polishing the lowers? Do you lose hydrodynamic efficiency? Other than the maintenance issue, are there advantages or disadvantages?
