I used Sutherland Wells varnish on my wraps and on the third coat I'm getting a slight wrinkle after it cured. The first 2 coats were 3 parts varnish, 1 part thinner. The third coat was uncut and did seem rather thick. I was very careful to wick off excess varnish with a dry tooth pick and did not expect this problem. Has anyone developed a viscosity test for varnish to determine correctness for wrapping. also any suggestions for fixing this rod? (Dennis Bertram) When you film thickness is too thick, this happens. Having thick varnish only exacerbates the problem. Allow the varnish to cure, sand each side of the wrap flat using 1200 wet/dry and olive oil, or raw linseed oil, reapply the varnish in a thinner layer. (Martin-Darrell) The question is how do you know you are getting a thin layer? Do you recommend thinning the varnish? (Dennis Bertram) Thin it, or heat it, or use it fresh from the can and toss it when it gets old. Use a small bottle to keep what you are using on wraps in and keep the can sealed as much a s possible, it helps to float a tablespoon or so of thinner on the top of what's left in the quart can. This is one of those things that can't be quantified, you have to get a feel for your material and what consistency you like it to be for yourself. (John Channer) An additional good measure, when removing an amount of varnish to a smaller container, is to drop a few marbles into the original can, bringing the level of the varnish back up to the top. This helps to minimize the amount of air (oxygen) available for interaction in the resealed can. (Bill Harms) Also on the application, I put it on, then clean the brush in solvent and wipe it dry, then brush the wrap again soaking up any extra on the wrap. (Chad Wigham) When MD says let it cure, REALLY let it cure before touching it.. If it's not really cured, you get the dreaded white "worms" that are tough to get rid of. (Jerry Madigan) Good point, Jerry. Yes, let it cure well. The varnish will get thinner the older it gets, and will settle down considerably, leaving you the ridges of the wrinkles. It will all be easier to sand then, too. What you may not like is the amount of time that transpires while you're waiting on varnish to cure. Go outside and watch the sidewalk crack. That will take your mind off it. (Martin-Darrell)
