Diamond valve lapping paste
Same paste we use in the workshop
Water based diamond lapping paste – Large trade pot
Not to be confused with the usual coarse/fine grinding pastes that are available, this water based compound is mixed with diamond particles and will halve the time it takes for lapping in engine valves!
Gives a nice matt finish to valves / seats so it is easy to see if it has a concentric seal – Please see before and after pictures
Smaller pots also available
