Re: Stus-List Reinstalling plexi windows...again.

[Gary Russell via CnC-List]

I used the darker of the two grey tints and there is no need to paint.  You
cannot see the gelcoat damage and I think the darker tint looks classy.
The darker tint has minimal effect looking out from the inside of the boat
but makes it very difficult to see in, unless there are lights on in the
boat.

Stus-List Short section of "old style" rub rail

[Chris Hickey via CnC-List]

Hey folks,

I'm trying to find a short (1') section of old-style rub rail (1972-84) for
a small repair to the aft of my C&C 30. I know South Shore Yachts carries
full 40' lengths, but that is way more than I need at this point. Would
anyone happen to have some lying around that I could purchase, or point me
in the right direction?

Re: Stus-List Reinstalling plexi windows...again.

[Derek McLeod via CnC-List]

When I replaced my portlights on my 29-2, I became quite paranoid about the 
spray paint attacking the plexiglass and undermining its longevity. I tried 
looking at the technical data sheets for various paints like Krylon and found 
they contained chemicals that would theoretically harm the plexi. 

My approach instead was to use just Dow 795 for the entire job. The slightly 
tricky part was making 3/16”x3/16”x3/4” spacers with cured 795 to allow enough 
silicone between the fibreglass and plexi. The rate of expansion between the 
dissimilar materials being the concern, and having enough silicone thickness to 
accommodate that movement. I made up an mdf board shaped slightly smaller than 
the portlights to hold it in place while the 795 cured for 10 days or whatever 
it was. The mdf was wedged against the portlights against the lifelines. 

The 795 just appears black at the overlap and the portlights have held up for 2 
years of big temperature swings in Toronto, Canada.

windows, tape, etc. and this is the year I will do it!

Re: Stus-List Reinstalling plexi windows...again.

[M Bodnar via CnC-List]

  
  


I used dark tint on my windows - can't see in for the most part. 
  But, when the sun was on the right angle I could easily see
  through the plexi and see where I was not very accurate with
  spraying the backs of the windows.

In my case the fiberglass repair is a blue 2 part epoxy repair
  that I didn't bother to paint over so it's more visible.
Don't think it's worth trying to tape off the inside and spray
  into the edges I missed - but a little more care on the cut out
  would have been prudent.
If you want to test it spray some plexi then VHB tape  2 pieces
  together -- when you pull them apart you could gauge if there is
  any reduction in adhesion with your paint choice vs no tape.
