[Amel Yacht Owners] Genoa sheet track plugs


Mike Ondra
 

Hi Eric,

We are trying an alternative to the plastic plugs that deteriorate with sunlight.

After cleaning out the decomposed plugs and dust, we filled the hole with white silicone. We filled considerably higher than the surface of the track, and after it cured a few days cut off the silicone with a razor flush with the top of the track. It’s a pretty neat job, and we’ll see how it last.

Hi Danny

We had a double whammy in that there was gel coat cracking under the track where (we think) the backing plate had expanded AND the car inserts had disintegrated and needed replacing. We did it as part of a fit out in Tunisia.. even with an impact driver we still couldn't get the whole track off but managed to free the track enough to slide the cars off.
Heres the link to the video, time stamped at the track repair.. hope it helps

Hi Mike,

I tried that last year and after a while it shrank and dropped down below the track. I have a new silicone that I will be using.

I called GE and they told me what special silicone to use. I do not recall the name . I am not aboard Kimberlite.

Mike, Eric and all:

This is coming from my background as an A & P (FAA airframe and power plant mechanic).  RTV (room temperature vulcanizing) sealants, aka silicone, comes in two basic curing regimens;  acidic curing (Acetoxy or acetic acid) and natural curing.   The acidic curing is prohibited in aircraft as it is corrosive to aluminum structures (also applicable for aluminum structures on sailboats).  Acidic curing RTV is ok on fiberglass.  When selecting any sealant (RTV or otherwise) it is best to avoid acid curing type.  Dow 737 is a natural cure RTV that I use a lot on aircraft but there are others as well. I usually have to order it online (not hard these days) as it isn't widely available in chandleries or the Home Depot type suppliers.

Good information Gary.

Looking up the specs is see this product uses atmospheric moisture to cure. Don’t know if that is “natural”. No mention of “acid” cure.

Recommended for exterior aluminum glazing systems. Anyway, its done and we will see.

Thanks,

Mike

Gary,

   That is a good point about not using an acid based Silicone on Aluminum.  I have not used the 737 but will give that one a try thanks for the tip.  I do have long term experience with the Dow Corning 3145 Grey silicone caulking on boats caulking in large windows, deck hardware etc.. This is a Mil-spec non acid based caulking that can be used even for electrical work.  This caulking has higher adhesion and elongation qualities than any other silicones that I am familiar with.  The UV and weathering resistance is the best I have seen in a silicone but this only applies to the Grey (there is also a clear version which is also a bit runny) which colour wise blends in pretty well with the aluminum Genoa tracks.   My bulk supplier has a minimum so when I just need a small amount I normally buy it on Ebay, in fact a small tube arrived just today.

   Thanks Gary for sharing your knowledge base.  I especially like the slider seal that you came up with.  My boat has what may be the original slider that has become hard and the noise that the slider makes in use is almost blood curdling.  (grin)  I really need to get that changed this season!

Hi Eric:

I reviewed the specifications and data sheet for that product and it looks like their recommendation is sound.  It is neutral cure, and has good environmental exposure specs. 

Let us know how it works out.  I still have a full bag (a couple of hundred) of those plugs but I must admit that I get tired of timing them to length and installing them as they only last about 5 years.  I do believe that it is important to prevent water intrusion into those holes.  The stainless screws, aluminum track and mild steel backing plates is a bad combination when water gets between those metals. 

All the best,

Hi Eric:

I reviewed the specifications and data sheet for that product and it looks like their recommendation is sound.  It is neutral cure, and has good environmental exposure specs. 

Let us know how it works out.  I still have a full bag (a couple of hundred) of those plugs but I must admit that I get tired of timing them to length and installing them as they only last about 5 years.  I do believe that it is important to prevent water intrusion into those holes.  The stainless screws, aluminum track and mild steel backing plates is a bad combination when water gets between those metals. 

All the best, 
Gary S. Silver
