Zinc Stearate Sources?

[Stan Bidowski]

Does anyone know some sources for Zinc Stearate powder ( to use as lightweight filler )
to add with dope, etc.  I think Randy Smith sells it, but am looking for possible
local sources to save on shipping some mysterious powder in the mail to Canada.   
Is there possibly anything lighter that will work the same???
Thanks, Stan

I'd like to note that it's cornstarch. 

Randy Ryan talked me into trying Duplicolor high fill lacquer primer. Seems to work very well and sands very easily.

I buy the stuff in bulk from "The Lab Depot", in Alpharetta, Ga. Although they sell smaller quantities, I bought 5# and it was around $75 including shipping. Five pounds is an amazing volume, and almost certainly a couple of lifetime supplies. That quzantity was shipped in a 3-gallon plastic tub, enclosed in several layers of heavy plastic bags. I cannot imagine there being any difficulty in shipping to Canada direct from the company.

I have used Duplicolor lacquer Filler/Primer for several years.  You can get it in the large spray cans AND gallon cans.   It seems about identical to Dupont Fill 'n' Sand.

I am also using their Paint Shop Lacquers now since they are avaialble in quart cans and I can get it locally.  The down side is only 6 colors and clear (don't know if the clear or colors are fuel proof), but you can mix them! LOL!!  So far I have only  used clear urethane over it, but I am gong to test Sig Lite Coat and see how it works.
