[Rhodes22-list] leaks -- Thank You Stan

Fri Apr 13 12:09:35 EDT 2007

I would use a poly sulfite rather than silicone. I think Dow 4200 or Boat 
Life would work. I would also use some of that stuff that Rummy recomends. I 
would clean out holes (some use bent nail in drill) to knock out any rot. 
Tape bottom and fill hole with thickened epoxy. Let dry, Redrill hole 
(tapping is nice) with counter sink. Re-place hardware and lightly tighten. 
Wait one day and tighten hardware. - Wally
