that worn looking floor and the spinner chipping looks great mal, i've used maskol between coats to simulate chipped paint, but i've never really been happy with that because the maskol when applied always seems to end up with every chip being the same size and in 1/72 a little too big.
that floor looks dead right to me, with a slight uneveness of wear that makes it look totally natural
Yep, I've tried other ways and seen modellers try the salt technique but it just never looks right. I had read about the "hair spray" technique and thought that it only worked with acrylics. I was told though that it is the reaction of the hairspray with water that allows this technique to work. The problem for me though is that I use MR Paint, which is basically a cellulose paint. It dries very quickly so I did the chipping within the hour, I could probably wait only half that. It didn't seem to be working on the spinner so I use a cocktail stick that had paint on the tip to rough it up a bit and chipped a bit more on the spinner tip than I intended to. So I'm not sure if it was the hair spray or the fact that the yellow was painted on silver?
The make of hair spray may not matter, I have a large can of cheap stuff but it smells pretty bad!
