"I’m about 10 tops into a stack of 40 cedar tops I got from you, and whenever I want to start a new guitar, I just walk over and pick a top off the stack, and start building.
They are all that great! I don’t have to dink around with the pattern, or select the “best" one: I just start building. I love that!  I just wanted to let you know how much I appreciate your high standards, and what a pleasure it is to do business with you!"


KTM Water-based Finish

Clear water-based finish, 32 oz./8 oz. sizes.

KTM9 is no longer being manufactured. Our stock is aging and we won't be able to supply this product again. We estimate that the remaining life of the product we have in stock is a year or so. We have drastically reduced the price to move our existing inventory.

John Greven initially encouraged us to feature this urethane/acrylic from Grafted Coatings. KTM-9 is a self-cross-linking product and does not require any additives. It has the advantage of fast curing, the ability to be brushed on, is non-toxic, and cleans up easily. Further, it has superior clarity and depth, and once cured and buffed out it is almost indistinguishable from nitrocellulose lacquer. It can be quickly cured using infrared heat lamps if there is a need for speed. A quart will finish from 4 to 6 guitars. Because of its non-toxic nature, KTM can be shipped anywhere by any means with no special cost or labeling. We carry two epoxy pore-fillers that are compatible with this product, ZPoxy, and System 3 Epoxy Filler, that work great with KTM9.

What people say about KTM.

We also carry System Three Epoxy pore filler, that works great with KTM9. Both Mike Doolin and John Greven consider it integral to their finishing process saying that it really brings out the best in the KTM9 finish. 

NOTE: Some builders have noticed sinking around glue joints where Tite-bond™ is used. For this reason, it is highly recommended that you use a harder glue, such as our yellow instrument glue (FGX). It is also okay to use hide glue (FGH) or cyanoacrylate glue (FGHO). The manufacturer tells us that the development of a skin on this product is normal. Do not attempt to mix the skin in, just skim it off and use as normal.
