I'm doing some modifications with Tamiya epoxy putty (quick type) which I have used quite a bit before. The thing I always find frustrating with it is how hard it gets and subsequently how long it takes to sand out. I've noticed that other people use other types of putty for touchups and finishes.
I'm looking for a putty that is easy to spread out, and easy to sand out. It doesn't matter if it is 2-part or 1-part, although 1-part would be preferable.
I've used Bondo Spot & Glaze (Testors Putty) and really did not like it. It is very crumbly and also shrinks. Very hard to get a nice smooth surface out of. So if you can avoid these properties, all the better.
Thanks for your input.
