Thanks lot!

:: I'm not sure what the original construction layup was,
:: however, recommended weight for deck repairs would be
:: approximately 20oz for the outer skin (example, a 17oz
:: biaxial with 3/4oz mat on both sides). Something thinner
:: for the inner skin would suffice (10oz cloth with 3/4oz
:: mat on both sides), except in highly loaded areas.
::
:: I'm not sure how much mat would be required for a pure
:: mat repair. However, it would be straightforward to make
:: some test pieces.
::
:: Most importantly: use vinylester or equivalent for
:: repairs, not epoxy. It is much easier to work with, and
:: future vinylester repairs may not work as well on epoxy.
:: Unfortunately vinylester is not readily accessible in
:: small quantities (Svendsens has it by the gallon).
