SPOT FILLING A CHIP IN POLYURETHANE... HOW?

[splinters]

Hello all,

Have any of you "actually" filled a chip in Warmoth standard Poly finish. I don't want to hear the boring, unoriginal 'MOJO' BS.

I just want a simple way to fill a chip so that I can sand it level and take it all the way to my buffing arbor and make it disappear.

Thanks, Gary.

Superglue?

Superglue?

It's pretty much the best option.  The good cyanoacrylate too like Hot Stuff, not Krazy Glue.  Tint it to the right color and drop fill.

Hot Stuff is Dan Erlewine recommended. It comes in different consistencies. Get the one that's right for the chip.

Thanks alot guys. I was hoping superglue would work... but I didn't want to take the leap without some pro advice. Have a great weekend everyone!

Ha, I'm no pro.  :laughing11:

If there is any color at all under the glue, just use the glue to fill the void.

If you can color under the glue - do that, and then fill the void.

Coloring the glue itself is the last resort as it tends to destroy the properties we like in super glue - fast drying hard surface

Use the superglue in a non-humid environment if at all possible, and dont breath on it to dry it.  Go slow, in thin layers.  All of this avoids "cloudy glue" syndrome.  Also MASK all around the area in case you spill some, or it gasses out fumes that will cloud the surrounding finish.  Those can be rubbed out, but its best if you protect things to make the cleanup easier.

huh? Wow!  ya learn something new every day.

There are superglue accelerators that you use between layers to speed it up. I've filled neck dings so that you absolutely can't tell they were there. Superglue is still a somewhat "soft" finish so I'd go carefully and slowly with a power buffer. You really can get it invisible by filing it flat, then 1000 grit wet/dry paper to a hand buff.

If you go THIN on SuperGlue it gets very hard.  The secret is going thin.  Never tried an accel. agent with it.

I've laboriously applied coat after coat after coat on a black vintage pickguard (bakelite) to build up a entire tip that broke off.  I used the black superglue from StewMac.  Worked great, like adding layers of material back.  When it was all dried - after 20 or so coats, I let it finish, then drilled and shaped it.  Never looked back, but you could see a very faint line.
