TopBand: Bonding radials

[AA6WG@directnet.com]

Has anyone used the "exothermic" process to bond their radial system together? 
It is prefered over the usual soldered bond because solder will melt with the 
first lightning strike. Is there anyone who is familar with the process and 
can describe the tools and materials that are used. Also does anyone know of a 
good supplier or 2 who sells the tools and materials? 

Thanks, 
Joe AA6WG
