Omega General Help / Re: Rusty cills

"And I don't consider the sills to be the worst problem: anyone with crusty sills should have a damn good look at the chassis rails above the the back of the front-subframe."
Well said and as far as I am concerned, go around the car with a pointy stick and a 30cm length of string around prescribed areas and find out where the holes are.
It's a safety thing, no more, no less and the back end of an Omega can look quite scary when you think about it.
I also wish people would understand that chemical rust treatments only treat the surface and have minimal penetration so are no good unless you have ground out everything that's brown. I only use them as a primer on old metal that's saveable and has been attacked with all sorts of grinding tools and other more specialist chemicals first. Even so, nothing available on the high st goes anywhere near the car. The surface then needs stabilising and not just spraying with stone chip and underseal.
It's a filthy time consuming job and depressing at times but worth it with the quality of the results when you get it right.
