Deluxe Plastic Putty & similar

[Breaker]

Anyone else used these? Are they not meant to be sanded with a wet tool, as everytime I use water with my sanding sticks for a smoother finish it just seems to wash all the filler out.

The Deluxe Perfect Plastic Putty? I've found exactly the same thing. It works really well, fills smoothly, but every time I've used water when sanding it nearly always 'washes' the filler away. Now I sand it dry and use a barely damp sanding stick for the last smoothing stroke. Saying that I do like the way it works and the fact that its fine.
