Thanks for the comments guys

Time for another update; I've been plodding away with this PF restore when the weather permits, painting in extreme cold or rainy weather is generally NOT a good thing to do, as it usually leads to problems as i found out the hard way some time ago!! so lately i've taken to heating the garage and shining a 150watt floodlight onto the PF to warm the PF before spraying paint on, which seems to help a bit.

Ok, now some pics.. progress pics of painting of the double bonus/shoot again/ 5x inserts area. painting the white, purple and yellow. I had previously primered/filled around the inserts where the paint had worn away, and block sanded these areas flat with 400 grit wet&dry and windex ready for the paint.
