If you don't use CP on garnet it comes out a very distinctive, rich looking, 'black cherry' color. See approx what it will be by doing a test wrap, then applying alcohol to it. Before the alcohol evaporates you'll see the approx color. Looks very good on the Ti Chrome Rainshadow Immortals.
My first build was in high school, graduated in '58, did a few then and when in college, then gave it up for a long time. Used to order all the parts from Herters. Remember "Finest Procurable Quality?" Kids/work/rebuilding an old house. Did my first modern build as a present for my adult son, an avid fisherman. So he could experience a world class rod. I built a St Croix SCV 7' MF. He was pleased, but after we really looked it over, we found that I had misaligned the guides. What to do? Being "new" to building, I tried bending the guides into alignment. The guides were Fuji Y titanium guides, and those of you who have tried to bend one know, it isn't easy. And it really didn't come out well. I didn't know at the time I had damaged the blank (longitudinal cracks under the first two guides). My son used it for a few years with no problems, but then I asked for it back to fix it right. When removing the guides I found the blank damage. Only option was to carefully add a fiberglass cloth reinforcement at those points, straighten the guides to original geometry (again, a very tough job even off the rod), add the guides and rewrap. You would have to know what to look for to detect anything out of the ordinary with the rod. Son has used it for another 4 years or so, no problems, no detectible loss in sensitivity or other functions, and all is well. Since then I have built him another St Croix SCV , his wife one, one for me, and two Avids for two of his kids. All great blanks. The 70MF SCV is a terrific blank for tubes and other finesse.
The main moral of the story is, for first builds, don't use a $160 blank.
