Yes I sent OS an email asking what material was used for the plating process on the VG and they told me all they new it was ABL! So I found out on their web site posted below. I all so one time email them asking what air filter would fit my TZ and they said the one that comes with it and it does not come with one! Glade to see you got someone that is a little more knowledgeable then the two I got. [sm=spinnyeyes.gif]

We all know ABN is not very durable! This is why I will not pay $200 to $250 for a VG 30 when there are much stronger, faster engines at about half the price!

ABL
Advanced Bimetallic Liner. Specialized form of ABN. Instead of a single-step, single-material plating, the ABL Plating process is based on a layered approach made possible by two OS-developed hard-nickel alloys. The first alloy is used as the bottom (bonding) layer, to fuselage the top layer to the brass liner. The second alloy, developed for superior hardness, forms the top layer. Together, they create a barrier that protects the liner against excessive heat and wear.
