If it's a standard paper tube, you're probably talking about the glassine outer layer. It's going to be hard to patch the damaged areas without any sanding, risking doing more damage. You'll want something that's easy to sand, like Bondo Glazing and Spot Putty: http://www.autozone.com/autozone/accessories/3M-3-oz-Bondo-glazing-and-spot-putty/_/N-255s?itemIdentifier=540155 What are you going to use on the body tube surface before painting? Whatever it is, it should work for repairing the area as well.

I am in the process of sanding/stripping my DX3 (paper tubes) and got a little "enthusiastic" in some spots. In those spots the outer paper surface seems to be shredding, almost like the extreme outer layer of the tube is peeling off (looks a little like white glue peeling off, but there is no glue there). My question is does anyone have any ideas on how to get a clean, smooth surface for painting on a tube with this type of defect? The two ideas I have at this point are: 1. Build up the surface gently and thoroughly with automotive hi-build primer and sand, sand, sand 2. Apply a light coat of diluted wood filler (almost like a plaster skim coat on a wall) and sand until smooth I do want to try and minimize weight and maximize durability, but I'm at a bit of a loss on this one. Thanks in advance, and have a happy holidays! Park WarneNAR 94438 - L1
