I made caps for the brake cylinders when painting. These caps prevents getting paint all over the cylinder when painting. Tape does often not stay in place.
NOTE: it is possibe that an advertised item is no longer available, because sold earlier. The shop software does not keep track of the stock and as most items are unique it can happen that an item is no longer there. I try to avoid this by marking a sold item as "Sold" but cannot gurantee that this is 100% accurate.
