Okay guys it's a little slow so it's time for another of BB's UBIs.
RTV: My first experience with silicon sealer was around 1965. I was in the Navy and the guy in the tool crib came up with a couple of cases of a new product from Dow Corning. It was called "Aquarium Sealer" and came with instructions on how to build a twenty gallon aquarium with no steel corner supports...just this miracle glue.
Well we, being skeptical, decided it needed testing....so we glued an ashtray, full of course, to the shop lead's desk. Took about 1/2 hour of putty knife work to remove it. Great!
Then we had a PITA in the shop so we glued his Kennedy Kit tool box closed. That took him the better part of a day to get open but he was less of a PITA after that.
For a final, test we glued the door to the head (Gentleman's Facility) closed. Worked as advertised.
It was a couple years later when I first saw the stuff being sold as gasket sealer.
Anyone else got a story about Steve's favorite goop?

I was having a problem keeping my clips on my hood molding to stay in place. Mustang Steve said give RTV a try. I marked the hood molding with a pencil where the clips go when the molding was on the hood. I took the molding off and lined up the clips with my marks and Gooped the RTV on them. I let it dry a day and installed the molding with the clips and nuts. That thing isn't moving unless a I hit a deer or rearend a car...LOL.

I used it recently to repair a crack in the seam of a doughboy sand filter. MSteve recommended trying it.
the filter plastic is about 1/2 thick. I treated the crack like it was steel. I drilled out each end of the crack + widened the crack itself, then filled it with RTV and made what I call an "umbrella" on both the inside and the outside.
A sand filter has to hold between 8 and 20lbs of pressure (depending on how often you backwash) and it hasnt leaked yet.
My biggest fear was that being at the top of the case where its kind of open, that the RTV would get "sandblasted" but all I know, is it hasnt leaked yet, and Im thinking I might not even try to hunt down another tank over the winter.

Not an RTV story, but JB Weld...RTV's Cousin.
I was a MAC Tool Distributor and one day my truck was overheating. I took it to the shop that worked on it for me. He found that the Block had a small Crack in it and water was seeping out through it. We let it cool, with a Dremel tool, ground a V into the crack, filled it with JB eld. Let it setup overnight. Ground it smooth. Put the accescories back on the engine and it is still driving to this day.
The OLDER I get, the FASTER I was.....

I was an airdale and did the whole works on dry land. We actually had guys fall for the old "five gallons of prop wash" and a bunch of other foolishness I can't recall now.
Steve69, RTV is holding the rinky-dink horn button on my Grant Steering wheel...just three little dabs and it stays put butt (thanks Sal) can be pulled off if necessary.
JB Weld, Ron, is holding the computer in our 66 firmly to the underside of the cowl air box. I also know of a number of Model A's with cracked blocks that got the JB treatment. They weren't wrong about that "Better Living Through Chemistry " stuff.

I once had a Geo Metro that had been in an accident and broke the front engine mounting bosses off of the block, I had the bosses welded back on but in the course of doing that the side of the block warped slightly and the head gasket started leaking, I removed the head and found the low spot with a machine shop straight edge for checking warpage, I filled the low spot with JB weld and then filed it down after it had cured, I sold the car a couple years later and it was running great and no leakage what-so-ever.
That distinctive whine requires considerably more cash investment.

- It helps keep the aircraft pressurized

Standard repair for small tears in blade type door pressure seals on Boeing aircraft -
Cut a small patch of nylon mesh fabric big enough to overlap the tear in the seal on both sides. Apply a thin coating of clear RTV (Room Temperature Vulcanizing) sealant to the patch and work it into the nylon mesh. Spit on your finger and smooth the RTV out. Let cure for an hour or so. Pressurize the aircraft - no leaks.
Also, I have used the red, high temperature RTV in engine compartments on small aircraft to secure loose wires from chaffing on the engine mounts or other structures. Put a big wad of sealant on the structure where the chaffing is occurring. Press the wire into the sealant and let it set up. No chaffing.
One place you should NEVER use RTV is in fuel systems. I know of an incident where a guy was building a homebuilt aircraft. He wanted to go the cheap, easy route. Instead of fuel resistant sealant to seal his fuel tank, he used RTV. On his maiden flight, the engine quit, and he crashed. The RTV had reacted with the fuel, which caused it to break down. The sealant clogged his fuel filter, starving the engine for fuel. It was a fatal mistake.

I was at the other end of the country, at NAS Los Alamitos, CA. I was a TAR and did the whole time at Los Al except for A School in Memphis, 65 - 66.
I had a bud there that had a 409 powered 65 Impala. He carried a Hot Rod Mag in the glove box with an ad for "The 409 For '65" on the back cover. Lots of guys would bet money that Chevy only made the 409 thru 64...he won lots of bets with that magazine.
