Review on Performance Tool W86552 2 Piece Lapper by Dean Partybus

As soon as you apply the gum it starts to stick to non-ideal surfaces. It took maybe 4 valves before I could tell it was broken in. PROFESSIONALS ONLY TIP: You can remove one of the auction mugs by simply pulling on the stick. Magically you can use a 1/4" drill bit adapter instead of a rod! Just be very careful! Be sure to check the hardness between the inlet and outlet valves to get a good idea of how long the drill can be used.
