Fill n’ finish Thin formula is a non-creeping, water clear, non-brittle and flexible pro formula top coat, finish, and repair solution.

When filling, Fill n’ Finish Thin is perfect for less porous woods, like ebony, maple, some rosewoods and Koa, which require a thinner finishing product that will penetrate further. Also perfect as a top coat when using both Fill n Finish products as a complete finish.

• Use as a top coat over Fill n’ Finish Pro Formula for perfect base coat in build ups
• Suitable for small brush work and wick-ins for lifting inlays prior to clamping
• Use as a stain sealer
• Other uses include as a flexible top coat, for finish work on inlays, and on any areas that a brittle, thin glue would fail

• You can shoot lacquer right over Fill n’ Finish Thin with completely invisible results!
• No creeping and zero to minimal witness lines every time!

  1. 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!!!

  3. 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.

  4. 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.

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