[C320-list] Furthur Questions on Insulating the Engine Cover

Wed Apr 11 07:38:17 PDT 2007

Thanks for all the tips.

  I do have my engine covers at home and put the teak handle on last night.  Tonight I will finish cutting the insulation & caulking the hangers.  I bought some 3M 5200 BUT, very reluctant at applying it.  I went to the hardware store yesterday & the salesperson said Liquid Nail would work.  This morning I read the directions, and it stated not for ceiling use.  

  West Marine is on my list to stop at today to pick up some 3M non-permanent caulk.

  So, after shoveling SNOW I will be working on this project.  Four inches or so in the Milwaukee WI area today.

  ps  Thanks to all that assist with advice & make this association pleasure to be part off.  ALSO, the burgee's are extremely nice and of very good quality.  Mine where delivered this weekend.

  Good suggestion, I brought mine home to do them. In any event, make sure
that the temp and engine covers are room temp when you apply the insulation.
The adhesive might not work as well if it's too cold or hot.

Be carefull using acetone in an inclosed space. You would be well advised
to remove the cover and clean it outside.
