Well lets see. I need a grommet on the back because I hollow out the thing to get it lighter around 5/16 Dia. so you need a grommet to center the 1/16 wire and I also add things inside. As far as the front goes I could probably get away without one but the stainless wire hitting the alum. will eventually cause the paint to crack and 2 dissimilar metals together esp. stainless and alum. will cause problems. The front grommet's I think are nickle plated brass so not as big a problem as stainless. I make the rear ones out of titanium. I will this fall experiment on alum. grommets like justplugit suggested. It is funny I got one that is uncoated just naked and well used and dull looking. I polished it up with Mother's alum. mag polish and it looks brandy new, no corrosion. So it is the powder paint that is trapping the water under the paint. Probably won't use the powder paint again. Bummer because they look soo good with that candy powder paint. Maybe a light coat of your favorite spray paints and when it wear's off repaint like Bassmaster suggested. Paul
