    “I have been using Fill n’ Finish and MasterGlu superglues and found them to be as great as the accelerator. Superior in every way.”

  2. Scott Holyfield, Master Repair Tech, Glaser Instruments Nashville

    I love Fill n’ Finish and use it for drop fills all the time – I just love it. I’ve turned many people onto it too – it’s great. For polyester finishes and urethane finishes, it’s perfect. It doesn’t distort the shape when you accelerate it, which is the general problem with using CA glue on finish is when you accelerate it it just goes crazy, and you have to work yourself to death to smooth it out, and with Fill n’ Finish you don’t. I love it – it’s the best I’ve used.

    The Fill n’ Finish filler you gave me has changed my life, I swear! You can even use it on Nitro. There is no sinking, no white marks, and no circles. Finally!!!

  4. 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.

  5. Rich Guerrero, RG Custom Basses

    As a first-time project, I also did an entire guitar with Fill n’Finish. While it was quite the learning curve to do such a large area, I did a finish in days rather than weeks. So yes, I am in love with your products! They work for just about everything I can throw at them.

  6. John Underhill, Underhill Creations

    Nothing compares to Gluboost for finishing my wood turning projects. I’ll never use anything else.

  7. Edward Victor Dick – Owner, Victor Guitar, Denver CO

    Fill n’ Finish is great at touching up finish, whether it be scratches, cracks or dings. Fill n’ Finish fills, blends, and buffs much better than any normal finish. We also use it in our guitar building classes to fill binding gaps, etc.

  8. Ken Parker – Ken Parker Archtops

    When it comes to pore filling and ding dent repair, Fill n’ Finish is the ideal tool!

  9. Dick Sing

    Not only does GluBoost provide the clearest finishes on pens, I also use it to bond during small projects, and have only had the absolute best results ever. Best product I’ve tried!
