Never, ever - let me repeat that: NEVER use anything
other than Epoxy on your EPS foam-cored board! Styrene solvents in Polyester
and Vinyl-Ester products dissolve EPS foam. Even the slightest whiff of
Styrene, migrating through the minutest crack, will eat the EPS foam! Many $20.-
dings have come to me, requiring $50.- in core surgery, because someone thought
they could get away with it...

Say NO to duct tape!! Duct tape is a fabric and therefore
not watertight. Besides, it leaves an infernal, sticky residue.
Do not squish wax into a ding! It does not form a
reliable seal. It does, however, contaminate the area, so that a proper repair
later may not
To seal non-structural dings on shiny surfaces, use a
decal, or clear packaging tape, or Aluminum Plumber's tape.
For dings in rough surfaces (non-skid), or for deep
dings, use Marinetex, or Ding Stick.
Always remove surface gloss before applying Marinetex or
Ding Stick! Always remove the vent screw if any, and always wait until the warmest part of the day has passed before
applying Marinetex or Ding Stick. As the day warms, the air inside the board
warms, expanding in the process, and spitting out your repair. About half the
field repairs brought to me, leak, because folks get this timing wrong.
So - wait until late afternoon, clean the wound as well as
you can, scrape away loose bits with a knife, rough things up a bit with 60grit
sandpaper, a nail file, a piece of glass, whatever.
