Sanding a WM100
« on: September 11, 2017, 05:14:59 PM »
Hi guys. I am thinking about re-finishing a WM100. This guitar has a clear lacquer finish over a specialty wood grain - I'd call it quilt but I am not familiar with all the different names for these specialty grains. Whether flame or quilt, etc., I am wondering which way the grain of these types of wood are? How do I know which direction to sand for these types of grains?

The WM100 is an all-laminate guitar (essentially, a specially manufactured plywood). The outer layers may be VERY thin, so if it were me I'd contact Washburn's customer service department to get some guidance. There may be NO safe amount of sanding... :(

Cheers!!

Quilt maple top; opinions differ on whether it's a cap or just a veneer. The figuring is a distraction, but is probably laid the same direction as you'd expect from plain wood: parallel to the strings.

But I'd advise against refinishing it --
Quote
WM100/WM STANDARD/WM4 (U.S. MFG.)
- slightly offset double cutaway mahogany body, quilted maple top with wood binding, mahogany neck, 22-fret rosewood fingerboard with pearl dot inlay, three-per-side Grover tuners, tune-o-matic bridge, Schaller stop tailpiece, 2 Seymour Duncan humbucker pickups, two knobs (v, tone), three-way switch, Buzz Feiten Tuning System, chrome hardware, available in Cobalt Blue, Honey, or Trans. Bordeaux Red finish, mfg. 1997-2002
Retail price was $1,699. Even with significant finish deterioration & showing some wood, book value is about $500; if in better condition, $700+.

If you strip it, you lose at least 60% of that -- forever. More if you take off the headstock decals.

Should you be capable of creating a professional-grade perfect gloss finish, this adds nothing to value.

IMO, you'd do better to experiment on a BT-4Q, which can be had for <$100.

Took some time off. Successfully re-wired, and trying to avoid re-finishing. Can someone tell me what type of finish the WM100 was. Guitar List says the WM100 is from the Maverick series between 1997 and 1999. What type of finish was used during those years, unfortunately, was not listed. I am looking to use some of the Meguiar's products or possibly sanding pads around 12000 grit to lightly remove haze marks, but would research various techniques dependent on finish type.

There wasn't the whole "nitro fetish" thing going back in the '90s. The point of putting a finish on a guitar -- particularly a solidbody -- was to keep it looking pretty. I assume the final finish is a catalyzed polyester.

It could probably benefit from a light buff-out -- a polish, actually, unless there's scratches deep enough to feel, & you want to remove them. Properly, that means an orbital, pad, & polishing compound. Of course, you'll first have to remove EVERY last bit of hardware, which will take longer than the polishing.
