OK Tigerman!!
I think we need a reminder post every few weeks on it staying sealed. Hopefully we'll never get one that says it leaks again, but even then I'd to like know.
How much prep work did you do before applying that stuff? I don't know what should have been done but if I ever ended up doing something like that I would have been temped to drill some 1/4" holes to let the JB-like stuff to fill in to help keep it there.
So the prep work was as follows...
The good thing about this location is that the area had a nice ridge all around, which served as a natural attachment point, so there was no need to create additional anchors.
- Cleaned it with a brush
- Blasted it with compressed air
- Sanded it the area down with the included sand paper, which was very rough, creating deep scratches.
- Blasted with air again and cleaned it up once again with acetone.
- Applied the putty and let it sit for a while.
Thoughts out loud...
Based on my faint memory of school chemistry... (regarding the glue for aviation use)
The most common fuel used in aviation is kerosene, as far as I know (not including the private aviation). Kerosene is similar to diesel as in the length of the molecule vs gasoline. This means that kerosene should be less prone to evaporation and most likely not as aggressive of a solvent as gasoline. I am just trying to say that just because something is designed for aviation doesn't mean it is stronger or better. It should have higher production quality standards, but may not work well in the automotive section due to difference of its usage requirements.
