Standard Yellow-Grey 2-Part Self Hardening Putty

Just tried this stuff for the first time while building a USS Constitution. Had great results by following some of the pointers found in these reviews. Make sure you blend the two together well, and try not to leave a lot of excess that will need to be sanded. When dry,this is very hard and will take more than the usual amount of sanding,but I think that is a plus.

Have been using Milliput since the 80's. Have always been happy with the results.

If you're building a big kit, and I mean a BIG kit like a 1/200 Missouri, then you NEED this. In my case Trumpeter's Missouri kit actually needed almost the entire two bars to fill in weak areas and mold errors. If you do use this keep in mind that once it cures, it's like a rock. It's very hard to sand, so if you're one of those people who leaves a bunch of putty sticking out... good luck. It also works well for making hollow areas of your model heavier. A heftier model just feels higher quality, so I use this often as just dead-weight.
