James, you say you will treat the scuttle of your car "properly, not with cure rust rubbish". Is there a simple treatment you recommend for surface rust?
In the past I have used (not by choice) and witnessed others using cure rust products, this will often cause micro blisters in paint afterwards (not immediately but fairly quickly ) my uncle was a metallurgist and always told us to prevent rust or stop it getting worse it needs to be starved of oxygen / air , the simplest way of doing this is with a good quality cavity wax such as Wurth products, what I find is that the wurth product is so thin that it runs between seems on body panels before it solidifies therefore stopping any water or air getting into seams , there is great debate at the moment about chemical stripping of cars which is acid based, when the car is dipped the acid runs into seams and is trapped, as soon as water/ air comes into contact with it it will burst out in rust bubbles, trust me I've seen it happen on a MK2 escort that was done, I use either a shutz gun or I also have a proper cavity wax gun with lances and drill holes out of sight and fill box sections in the car until its running out of seams, the 1600HF we have just finished had 1ltr in each sill alone, a total of 6 ltrs were put into the car and probably 2 ran back out of it, waxoil is very good but not thin enough to run into seems and I tend to use that underneath where its good for a thick protective covering, its very simple but very effective , sounds too good to be true but honestly works,
