the other area i worked on which was pretty bad was the catman and spaceman's faces, which came up pretty good just with a scrub with isopropyl alcohol and Magic eraser. also i redid the areas just below their faces, by masking off and spraying new colour. Notice in the 1st pic, i have sprayed in the off white below Ace's face.. before i sprayed the colour on, i traced over the black detail markings first with a sharpie pen, and allowed this to bleed back thru the paint after it was sprayed on. This trick allows me to draw or paint the lines/markings back in later after the white has dried!! Its a trick i stumbled across by accident on an earlier resto, when i had to repaint a section that had sharpie ink, and it kept bleeding back thru the paint i was laying down  

well now i have learned to exploit this to my advantage  

Last couple of pics, a bit of a before and after   i still have a bit of work to sharpen up the detail a bit, but i was keen to post some progress pics!!

Also i still have to redo the black around the top bumper area and in the cauldron.. will be done tomorrow.
