Came here to post about Yield and found it in another post, about PB Blaster. I have since contacted the company and gotten a price:

$148/12 cans + shipping and tax.

1.800.527.9921 to reorder, can is marked not for resale. Chemsearch, a division of NCH corp, 2727 Chemsearch Blvd, Irving TX 75062. chemsearch/yield c=Case+Studies

Cuts rust, red or white lead, tar, grease, dirt, deposits of carbon, graphite, green corrosin, etc. without injury to basic metal, rubber paint or wood. Contains no acid, helps prevent further corrosion.

I got it when working at a bus company, used it to quiet my old bus. I'm about out, but I've got so much WD40 and some liquid wrench and some Marvel spray that I'll just hang onto the cans.

Does anyone know where the red straws can be obtained? thanks
