WTB: 33.8 Seatpost Clamp for Project Underground

I know this is an old post, but did you ever find a seat post clamp? Both Undergrounds I have have a 31.8mm clamp. The paint was all chipped up under the clamp so I drew a line on the seat post with a pencil around the bottom of the clamp and took all the paint off under the clamp. I touched up below the line and then clear-coated. The 31.8 clamp fits perfectly. The paint on those frames is THICK!

I used finger nail polish I got it at Wally World to touch up. It's called Pure Ice, Strapless(label on the bottom) is the color. It is a dead match for the blue, but the metallic is just a little smaller than the original. I gave it 2 thin coats of the fingernail polish below the pencil line and I used Krylon Triple Thick Clear Glaze for the clear coat. I taped all around and covered everything with cloths before spraying the clear and then removed the tape immediately after spraying. I went over it twice with the clear. After it dried I rubbed it out with Meguiar's Scratch X 2.0 to remove the tape line.

My daughter laughed at me because I went to several places in the mall and carried the frame inside to help get a good match. I went through about $30 and 6 different colors before I went to Wally World and found the match. The funny thing is, the nail paint seems to be tougher than the original paint.

I remember seeing the Sinful Color mentioned and looked everywhere for the color, but couldn't find it, even though Sinful Color is still made. Before I found the Pure Ice color I went through about 6 different colors that dried with a purple-ish tint.
