repairing cracks in...

[Farrell]

Hello Roger,
   I use West System epoxy products in many applications, but am not
familiar with a "water thin" resin/hardener. Do you have a product number or
any more specific product designation. Their #105 resin is about as viscous
as motor oil, so I assume you are talking about another type of resin - or
do you thin the #105 resin out somehow? (Would that not affect the final
strength of the epoxy?) I will also be resetting bridge pins and can easily
see the advantage of a truely "water thin" epoxy. Thanks for any info.
