Would appreciate some advice here. I noticed using a hydraulic rivet puller I was getting a lot of marring on the pop rivet head. After grinding the rivet puller nose smooth because the hole was not very clean I didn't get much improvement. I bought a new puller which has a better sized nose piece for the LP4 rivets. Rivets are much improved but still some marring. I tried reducing the air pressure, moving the black barrels inside the rivet forward. Is there a trick I'm missing.
