If you are asking about where to buy caulking tools then you can buy them online or at any plumbing supply store...

Here's a couple sites:

Unless you are taking up the trade I'd go with an alternative. Alternatives to Lead Seal in Cast Iron Drain Pipes | eHow.com (http://www.ehow.com/way_6558606_alternatives-cast-iron-drain-pipes.html)

I completely agree with Ballengerb1... ;)
