2220.0. "looking for waterproof adhesive" by TRNADO::BREAU () Tue Jun 13 1995 18:03

 My Tornado cat needs to have the tape for the centerboard slots replaced and
 I'm looking for suggestions on adhesives. Some members of our fleet have 
 successfully used a waterproof contact cement named GRIP but we can't seem 
 to find it anywhere. One advantage of GRIP (or any good waterproof contact
 cement) is that it is easy to remove whenever the tape needs replacing.
 Water resistant contact cements such as Jasco don't work - it needs to be
 totally waterproof. Anyone know where I can find GRIP or other waterproof 
 contact cements?

 If I can't find a contact cement then I'll consider other adhesives. Expoxy
 tends to be a pain to remove but I'll consider it. The surfaces to be bonded
 are fiberglass gelcoat and a mylar laminate. The adhesive also needs to be 
 quite strong as the centerboards are raised/lowered several times during a 
 race. Any suggestions? 

   thanks,

2220.15200 isn't really removableMILKWY::HEADSL::SAMPSONDriven by the windWed Jun 14 1995 09:2618
 My first thought as I read your note was 5200, but then you said it 
had to be reworkable. I know that 5200 can be softened with heat, but I have 
no idea how that would effect you gel coat. I think a heat gun will work, but
I don't know if a hair drier would be enough. I just replaced spinnaker
pole ends which had been glued in with 5200. I was absolutely amazed at 
how secure those ends were. After heating the area with a propane torch I
was able to get the ends out. This is not a method I'd use on any of my 
fiberglass. It takes a day or 2 to set, but the glue is there to stay. I 
certainly wouldn't think about putting the board down before the stuff was dry. 

	Hey, what is this tape stuff?? Where is it applied? We have a new (to us)
F-27 and there is some slop in the board and I could still improve on the 
kick up rudder. Is this tape something used to fill the gap between the board 
and the trunk to take the slop out of the board? Is it availible at most 
catamaran shops? What is it made out of? I think I'm very interested in this 
stuff.

 The centerboard slot tape is used to cover the centerboard slot opening when the
 boards are raised to improve downwind performance by reducing drag -> no open slot
 and a relatively smooth surface that matches the hull shape. There are actually 
 two sections of tape on each centerboard slot - the board slides between the two
 tape sections. About half (lenthwise) of each tape section covers the slot opening
 while the other half is attached to the hull surface that surrounds the opening.
 The material has a smooth (outside) surface and a textured surface which is bonded
 to the hull. It comes in 2", 3" and 6" widths. Some Tornado sailmakes carry it but
 I just bought some from Layline (800-542-5463).  Same exact tape and less money
 from Layline - about $1.55 per foot for the 3" tape.
