Any question answered...

I did my first ones at the end of the summer.
Had used tape before. I'd say the bond is definitely stronger with cement.
I used the continental stuff and followed their instructions, but squeezed their crazy long 2 day process into 2 hours.
Worked like a dream, on straight and no mess. Did cover the floor in newspaper before I started though.
Make sure you remember to sort out somewhere where you can hang the tube to let it dry between coats before you have it in your hand and have to sort something out one handed!

Any reason not to put the tub on a spare rim the "wrong way round" as it were, with the base tape facing out, and just paint it with glue that way?
