Step 10Clamp It

Clamp It
To make extra sure, I'm using C-clamps (G-Clamps in other countries) to maximize contact while things set up. You could also stack some books on it or whatever is handy.

After an hour or so I took the clamps off and put the thing in the sun to drive off the braindamage solvents.

And that's it! It holds air and works fine!

If your patch leaks you can heat it up with an iron or hot air gun and squish it down. The melting point of the cement should be slightly lower than that of the sheet materials.
If that doesn't work, you can either peel it off and start over, or patch the patch.
