New putty trick

[Spruslayer]

This may be old news to some but i just stumbled on the best putty filling idea that works flawlessly.

I never could get the edges to feather up nice a clean before \

On the L-700 TAT build im doing, i was using the putty to fill in the area i put the cab hinge tube in and thought to myself,Self, that putty looks porus?

So i thought why not cover the putty in water thin ca,cure over night and see how it works and sands

I take Bondo spot glazing putty and apply it to the seam or what ever else needs filling.

Let that cure over night.

Cover the putty aera in ca,cure over night and wala!

It sands and works almost like its styreen

Been doing it for years. Another advantage is that (assuming you do it on DRY, HARD putty) is that it sinks in and hardens and stabilizes the putty, so it doesn't shrink and shrivel up years later. I do it after I've sanded the putty to final shape, and then give it a final sanding after the CA has cured.

Thanks for the tip! I have not been happy with any of the puttys I have.

I have not used either of those products, but I have done that with Squadron putty and regular CA glue.
