Why won't my Milliputt dry?

[Mustangman25]

Hey everyone
I just bought some Milliputt, and used it for the first time the other day on my Eclipse that I'm building. I applied it Sunday afternoon, and come Sunday evening, it still wasn't dry. I thought that the humidity of the basment may have had something to do with it, so I brought it upstairs, so that it was sitting in a low humidity, room temperature enviornment...I can still see my finger prints when I push into the putty with a small amount of force. Does anybody have any idea what could be causing this, or how to fix it? The two parts were thouroughly mixed, no streaking, etc., and I continued to mix them for another minute. Any help would be great. Thanks in advance!

you only waited for a few hours? u gotta wait a lot longer.

The box says in "Rock hard in two to three hours"...unless I misread 'days' for 'hours' without my glasses...

I am not particularly familiar w/ "milliput" but if is a two-part putty you want to make sure you mix it evenly; sounds like there is not enough hardener. Also I always let my big putty jobs dry for at least 24 hrs. to allow for shrinkage, curing, etc.

i dont think you should pay attention to what the box says. yes, you should make sure that you have the same amounts of each part and mix them evenly.

I threw my packaging away but I'm fairly certain it said "Cures in 2 to 3 hours, rock hard in 24 hours". Either way, I don't touch it for at least 2 days.

I love Milliput, it´s sooooo useful. Anyway, besides blending it more exactly i order to make it hard, just put it under a lamp, that really speeds up the process. And if I may I´d like to give you a tip on how to get a great, smooth surface immidiatly unless you already know this (took me a while to figure it out). Simply use a lot of water, NOT when you apply the putty though, that will only make it slide around. When you have it in place, fill a bowl with water and hold the piece that your working on over the bowl, then just wet a finger and start rubbing on the putty, just like when using abrasives. When you´re good at it, you won´t have to use any abrasives, well at least not until a p2000 to get a shiny surface. But back to the hardening problem, when you´re happy with your "finger-grinding", put a few drops of water on top of the puttied surface and place under a desklamp for 1-2h. after it should be able to polish, if not there´s gotta be something about your blending.
