I built my -7 rudder (yes, it's the new design) with no sealant at all. The only reason sealant is mentioned in the plans is to hold it straight. If you have a good straight work table, and a good handle on your riveting, it should be fine. Just remember to start out lightly, working back and forth about every 10th rivet. This will allow you to correct any waves that start. Mine turned out straight as an arrow, and a local -9 builder with no previous experience did the same thing. Turned out fine! Just an alternative, not the only way to go.

Permatex is the brand that seems to be most common, such as: http://checkoway.com/url/?s=fa45f5f6 Don't know what area you live in, but around here the auto parts stores are closer than Walmart and more prevalent. 8-) )_( Dan RV-7 N714D http://www.rvproject.com ----- Original Message ----- From: "Allen Fulmer" Subject: RV7-List: Any substitute for RTV on rudder stiffners > --> RV7-List message posted by: "Allen Fulmer" > > About to close up the rudder skin and don't have any proseal or RTV.

Go to an automotive store and get a silicon that's non-corrosive to aluminium. They sell it for engine gaskets. ----- Original Message ----- From: "Allen Fulmer" Subject: RV7-List: Any substitute for RTV on rudder stiffners > --> RV7-List message posted by: "Allen Fulmer" > > About to close up the rudder skin and don't have any proseal or RTV.

Is there an acceptable substitute available at the local hardware store or Walmart?" =========================================== I wouldn't suggest RTV. I have seen instances where the vinegar (acetic acid) in RTV silicone eats at the aluminum as it cures, causing a poor bond that allows for leak in the future. This is very prevalent in motorcycle engines and VW engines. Acetic acid and aluminum don't co-exist well. Perhaps 3M weatherstrip adhesive would be a better choice of locally available adhesive (wal-mart, auto parts, etc). I do not know if pro-seal is the recommended substance, but you have come this far, why not just get the right stuff and do it right??? Is it worth it to you to always have the thought nagging in your mind: "I should have just bought some pro-seal and did it right". To me, I like to make sure I did it right the first time, with the right materials. Happy building, Linc
