I am very happy with the modelling putty, this is the first time I have used the putty on my models and find it an excellent replacement to the Vallejo modelling putty which I have been using for years.
The putty is easy to apply and clean up, if you applied more than required, and sand when the putty is dried. Although I have just started using the putty and the tube is full, I imagine being able to use all of the putting in the tube would be easier than trying to get putty out of an old Vallejo "eye drop" bottle.
