"There isn’t anything at all that I don’t like about MasterGlu and Fill n’ Finish! GluBoost especially is just the coolest - it’s the best accelerator I have ever used. It doesn’t distort the glue, and it just works better - it gives you a better result as far as the texture of the glue goes and the work that comes after it - if you accelerate glue with the usual stuff you’ll have to sand and sand and sand to smooth it out. With this you don’t and that’s awesome."

Scott Holyfield, Master Repair Tech, Glaser Instruments Nashville

"We love Gear Up's cyanoacrylate products. Their stuff is definitely the best out there."

Paul Janowski, Director of Operations, Blackbird Guitars

"Gear Up Products are awesome. I’m using MasterGlu exclusively for all inlay work."

John Gaudesi, Director of R&D and Master Builder, Schecter USA Custom Shop

"We at Wilkins Guitar Finishes use Gear Up Products for many different applications. The MasterGlu and UltraThin are our go-to glues when the finish details have to be perfect. The Fill n' Finish is #1 for gap filling and touch ups when needed. The GluBoost is the best product I've ever seen for setting and hardening all of the Gear Up products that we use. Thank you guys for creating a wonderfully usable product."

Pat Wilkins, Wilkins Guitars

"I've been using "super glue" for about forty years now starting with Eastman 910, and the Gear Up products are the best yet for sticking stuff together, repairing bits and pieces, and fixing finishes."

Rick Turner, Legendary Luthier, Turner Renaissance Guitars

"With the kind of inlay that I make it is so important for me to have on hand the most reliably trusted products on my workbench. When it comes to cyano-glues and accelerators, I've used them all. The brand that tops them all is MasterGlu Ultra Thin and when used along with GluBoost, they make a great pair and their Fill n' Finish Pro Formula is also terrific for finish detailing."

John Monteleone

"I love GluBoost. I never thought such a small thing could make such a difference. We never have to worry about those nasty little white spots again. "

"GluBoost is awesome stuff. It works so much better than other kickers. And it smells better too."

Kenny Dennis, Top Coat Manager, Paul Reed Smith Guitars

"GluBoost accelerator always gives me the quick cure time and clear finish that I need. And when it comes to, pore filling and ding dent repair, Fill n' Finish is the ideal tool!"

Linda Manzer

"I love these products. Fill n' Finish is a real game changer for finishers because it blends beautifully and invisibly with my finishes. Thank you."
