Tamiya 2 Part Polyester putty mixing ratio

[Haubenschild]

Hello , I am just wondering what the mixing ratio of putty to hardener is. I tried using some 3 hours ago and it still hasnt hardened.

Thanks

That's one of the reasons I like that putty for some specific uses. In using up some 3 tubes over the years, I have found that a puddle of putty about the size of a quarter,to a spot about the size of a pea or less is a good start. This polyester putty is not like the more common one (evercoat,3MBondo etc) doesn't kick quite as fast. I usually give it a good 24 hours.

Oh wow. I thought it would set in a few hours . Thanks for the help
