What does it feel like?
On the photos it looks its it 5mm thick or more so it'll take a while to dry.
It's slightly tacky in parts, but parts of it look much better. It was my first time using the WaxOyl to underseal the car like this so i'd probably do things differently if I was to do it again. I'm going to be driving it tomorrow (work, unfortunately) so I hope I don't lose any of it before it dries.

In terms of sealing the inside of the sills how is this done? I was advised to run the tube into the square hole that is often used for jacking the car up with the Rover jack, however there was no room to feed a tube up into this - it was sealed. Does anyone have a picture of where I would put the tube?
Cheers.
