prep and prime
Now get some degreaser does have to be anything special (i used flash kitchen degreaser with grapefruit, nice:yum
Now once dry get some Wet and dry (medium grit) just to smooth and allow the plastic primer to stick better. then do the same with a bit finer grade grit wet and dry.
I used a halfords paint prep wipe to remove grime, oil, wax etc. you can find them in halfords near the paints. very handy for a good finish!
now get you plastic primer (im using a hycote spray £3.99 wilco direct) shake for around 2 mins. Spray lightly across the handles then leave for 15-20 mins then repeat 3 to 4 times till complete covered. LEAVE FOR 24 HOURS or you've just wasted your time and money. its hard to just leave it but you have to.

They are getting there!!!
