Diamond valve grinding lapping compound paste – tester Diamond valve lapping paste Very small 25g pot ***Please note – colours/type of container may differ due to availability*** Same paste we use in the workshop Water based diamond lapping paste – very small pot Ideal if you only a few valves to do, enough for a full 8v cylinder head 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 – Please see before and after pictures
