It's no better than painting to prevent rust , on some places on cars I've stripped it's acted as more of a water trap than protector and rotted floors .

True, everything starts from seeping seams between the spot welds.

Hi there its also on the underside of stainless steel kitchen sinks. if you take it off a sink then the sink goes rusty after a while. don't know what its made of though.

The sink ain't made from stainless steel and that's a fact.

very curious stuff.

You sure the stuff you're thinking of under the sink isn't the vibration dampening material?

aye, but the stuff in my rangie stops rust dead, even on the other side of the metal. Bizarre, but true!

It's a self adhesive bitumen pad. That first picture is my Range Rover

woo! Internet makes it a small world. I followed that thread on the other forum.

The pad on the sink is to stop the drumming sound of the water hitting the bottom of the sink in stainless and alu sinks. It also stops the rusting of steel sinks.

According to the boffins in the lab the pad is indeed bitumen with increased petroleum content. This probably explains the discolouration of the steel and the lack of rust on the other side of the metal. The sample was completely waterproof and also allows no oxygen to pass, hence absolutely no rust.

The mixture of those pads is no longer used in cars due yo it being highly flammable.


so there.

You had a lab analyse it? .

I've got some onions down the side of my seat that fell off a cheeseburger a while ago, can you analyse them and see what's living on them?

Aye, I mentioned by brothers bods would have a gander at it. I kinda got into a silly argument with my brother and it ended in: " Right....I'm taking it into work and have it analysed....and that will be the end of it". :lol:

true
a sinks metal has nickel and tin and loads of other crap in it!
its that stops it rusting and theres no chemical on eath that can prevent steel rusting without even touching it! im talking about the other side of the metal
