Description

Diamond valve grinding lapping and compound paste – Large Trade Pot

Same diamond paste we use in the machine shop.

Water based diamond lapping paste – Trade pot (100g)

Not to be confused with the usual coarse/fine grinding pastes that are available, this water based lapping 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.
