I like to use the Graphit 33. It has fixed my whole Plus4 keyboard.

I have also purchased an A1200 keyboard foil which had the caps lock key 
pad slightly offset and I have used the Graphite to enlarge those pads. 
It works perfectly.

You can spray the paint to a cap and use a brush to paint the pads with it.
