If I go out there with a claybar, I'll end up claying the tiles on the floor, lol.
It's only a PVC roof you know...
I still got the following things on my snowfoam to do list:
- A van
- A truck
- bicycle
- neighbours cat (all three of them...if that don't stop them shittin in me garden, then god knows what will....)
You forgot about naked ladies unless of course you have already squirted your foam over them
Prolly have to get ph neutral stuff then, but the danger in that is that afterwards they might not be "filthy" anymore and just walk off after.....
They'll hang about for a hose down!
