Hi Fernando,

Thanks for recognizing the K-Factor as having valuable information. The gentleman who wrote the 3M 170 article really did the engine and 3M justice.

That said, this issue of the K-Factor will probably be made available for public download several months from now. If you ae not currently an active member of the NSRCA, you wil be able to attain it then. If you are a current member, I'm sure that the NSRCA secratary would gladly email you your member ID and password to down load it now.

I realize you are from Chile. I believe the K-Factor will mail internationaly if you are interested.

Thanks,
Jim W.
