Finally riding a big boys bike
Working on a Columbia which appeared to be stripped of paint long ago...
Steel is in good condition howver to better true the high visible tubes I am using a flat file to rasp the tubes to better true the shape, remove minor bumps, inperfections and minimize need for much primer filler. Can also use a rat tail file.for concave tubes.
Power tool sanding is often all to much abrasion and flattens round tubing (although I do that at times)
BTW- I first use 80 grit 1" wide sand paper to push/pull wrap the tubing for removing surface oxidation "particles" buildup.
I always use a chemical rust remover or converter to dereust into the metal pores..
Painting is 90% prep and 10% painting...cheers..
