I am not an employee for westlube, (Westland Products Company) but want to share information that may assist you in your conversions. If you have a lot of holes to drill in any kind of materials, stainless drilling or machining to do or tapping to do, try this product. This product was also recommended only a week ago by another bus nut but the manufacturer offered me a deal today that he does not mind me passing on to you guys and I feel I should let you make the decision to ("Deal or No Deal") you might say.

This is the address for "Westlube" lubricant for drilling, machining and tapping difficult materials or any material needing this done. The representitive (Bob) said that he would send 6 - 8 oz. wide mouth jars, (This size design packaging discontinued because of new packaging design) for $20 plus $10 S/H. This is $15 dollars less than normal and his price is going up very soon. He will also include a squeeze bottle for you to use to apply if you wish. Go to his site above, send email and deal from there on your own, only let him know the owner of (The Rustless Money Pit) recommended you contact and use this product for difficult work for sure by hand. Six bottles of this lubricant should last a normal converter maybe a lifetime but the price is right if you do this often.
I hope I am giving you good information to assist you in your conversion.
