Hi Mike,
Not really, but I see your logic!
The problem seems to be that when I heat it too much, it kinda melts(which is normal I think
) and you scrape it, it then smears into a very fine film or tar. You take the majority off, but there is that little bit that stays behind. If I warm it up just enough, I can scrape it quite clean. I recon that is the reason why it took me that long to do so little.
The other reason is I dont have a Oxy set-up
If I had, I would probably cut the floor out, lol.
Hopefully today I can get some more done.
