Lynn,

    Advice please..............I have choice of 120 to 800 grit lapping compound from

an industrail supply (Travers Tool Co. Inc.) and would like to know what you would

recommend..............One pound containers are currently on sale for about $20.00

for 120 to 400 grit and about $33.00 for 800 grit thru Dec. 31..............

 

I only used valve grinding compound, so, a guess would be about 300 grit..............
