Metal Glaze Putty Hardness

[RyanR0101]

I've heard Metal Glaze is the putty to use.  My question is how hard is it supposed to get?  I bought a brand new (verified by date code) container, mixed some, and I can scratch it with my fingernail.  Is this the way this stuff is supposed to be, or is it supposed to be rock hard?  I've tried less catalyst and more, with the same result.

It's a 2 part polyester glazing putty, it should not get rock hard. It should remain sandable and easy to feather out.

Never heard of it.  You might want to try 2 part Bondo for big jobs and Squadron putty for tiny jobs.

Metal Glaze is simply Evercoat's brand of 2-part polyester finishing putty, pretty much identical in chemistry and performance to all the other catalyzed putties.

It's a premium product, and works very well for big cars and little ones. As stated above, it isn't supposed to cure "rock hard". If mixed correctly, and there is some latitude as far as mix ratio goes...but try to stay relatively consistent...it will sand and feather easily, with excellent adhesion to the substrate.

The small metalized 'bag' container available from Metal Glaze is probably superior to the small 2-part Bondo container for modeler use, as it does a better job of inhibiting drying out of the product over time.
