i don’t know them , i use dinitrol , 60£ on ebay for 4 cans plus an applicator , worth paying about 5£ more and there is a cavity applicator , ive thrown my waxoyl stuff out as this stuff is much better plus easier to use

 

What do you do to the surface rust?

How do you clean the underside of the car 1st?

 

A mixture of a wire brush plus a drill with a wire brush end , take it back to rust free , then spray , they do loads of products including some sort of stone guard , it’s very easy to apply , if it has protection on the underside and arches, and it looks good i leave alone or put a cover over it , but as with all factory under sealing areas are missed , jacking points got an extra heavy dose

 

Shrek have a look at this company I have personally been using their protection against rust for years now with excellent results ...https://www.bilthamber.com/.SJ.

 

cheers buddy but ideally looking at a drive in - drive out place to do it for me. i will speak with the clinic to see if they are still doing it.
