The best, quickest, and least messy alternative is to use nothing.
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.
Cheers,

RTV is available at any auto parts store, at least most of 'em (Kragen,
AutoZone, Pep Boys, etc. in this area).
Permatex is the brand that seems to be most common, such as:

Don't know what area you live in, but around here the auto parts stores are
closer than Walmart and more prevalent. 8-)

RTV is just another word for silicon sealant. Go to an automotive store and
get a silicon that's non-corrosive to aluminium. They sell it for engine
gaskets.

Allen:
I'm not sure about substitutes, but most all auto parts stores
carry Permatex "Blue RTV Silicone" in tubes that are about the perfect size
for the stiffners.

"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
