I'm not a very "clean" modeller. Some people seem to be able to models that look immaculate even when unpainted. Mine, on the other hand, are covered in blobs of superglue and badly sanded down filler.

I've sprayed the J with a light coat of Tamiya grey, which has exposed all of these rough bits. I'm leaving it to harden overnight, and then I'll make a start on rubbing it down and getting rid of the mess.

I'd normally use red oxide on a loco, but the grey is intended to make it easier to position the grey rivet transfers when I come to do them.
