I bought this Putty to try out. I found that the Wood Putty that you get from the Hardware Store, like Plastic Wood tend to be a bit too crumbly on application. And also I’ve had trouble with chunks flying off while sanding. So I was looking for a stronger Putty.

Well, this one I think is made for Plastic Models and it is super strong.

You need to be careful while applying it with your fingertips. This stuff sticks to your fingers like nobody’s business! I’d wear some gloves to apply with fingertips. Like surgical gloves.
