i used a tiny bit of auto body filler to fill the holes, same as i did on my Quickdraw pf.

Once it had dried i carefully sanded it flat with some 80 grit sandpaper, some of the lettering WAS removed in this step, which was hard to avoid!

3rd pic shows the yellow touchup, done once again with waterbased acrylic, the colour i used is called cadmium yellow, and matched pretty well, it looks better in the flesh than in the pics

And finally the missing/damaged text was re-done, using the same fluoro pink i did the other touchups with, i just sprayed some paint into the lid off the spraycan, and painted the text back in with the fine brush. It took some time to get it to look the way it does in the last pic here.. was fiddly to do but i think i have it to a point where it looks acceptable.
