Refret Refinish 1 2 3 — Lac R' Shot UltraThin Flash Coat can with acoustic guitar

Refret Refinish 1 2 3!
GluBoost’s Lac R’ Shot UltraThin Flash Coat brings the spray booth finish to an aerosol can.

Now quick and easy professional repairs of gloss finishes after repair work is attainable — plus complete ultra-thin gun-like finishes are also now doable right out of a can.

Lac R’ Shot! UltraThin Flash Coat provides an ultra-thin, ultra-clear, hard and durable nitrocellulose finish that is more flexible and far more chatoyant than any competitor’s lacquer. With an adjustable Vertical / Horizontal spray nozzle coupled with a specially-tuned “even flow” formula, you get gloss flash coats as close to a spray booth as you can get without the artillery.

GluBoost makes your work faster, easier, better. Guaranteed.

Why It Matters

For refret work in particular, the tedious part isn’t the frets — it’s getting the finish back to flawless afterward. Dropping a spray booth into a small shop isn’t always practical, and brushing nitro is a different animal from spraying it. Lac R’ Shot aims squarely at that gap: a gun-quality nitro spray pattern you can pull off a shelf, nozzle toward either axis, and lay down on a binding strip without gear you don’t have room for.


Great for both large and small pieces. A superior spray-gun-like ultra-thin lacquer, finally — right out of a can.
