Car rust products

Got rust on one old car and was wo dering if there is a really good product that works.

Have been using Krust from hammerite and it converts the rust to black but when primed and painted it bubbles out through the paintwork again in under a month

Jenolite is good but similar to krust. The big issue is you have to grind/wire brush the metal to physically remove all the rust and make the area shiny and then you can apply the liquid to kill any rust in little pores and pockets, its no good applying to a large area of rust and calling it a day as it bubbles back up in no time.

Good zinc primer then and a proper topcoat

If its only surface rust I have found Lanoguard quite good. Have it all over the underneath of my 92 T4, easy to apply and doing a great job!! No good on areas that can be seen tho as it sets waxy and you can't put anything on top of it.

For the areas that were a little bit crustier I wire-wheeled and applied FE-123 rustbuster converter before the lanoguard.

The FE 123 Seems to be good stuff - to test it I put some on an iron post of the shed that faces the worst of the weather last winter, it had lots of surface rust on it before I applied. You are supposed to prime and paint over the Rustbuster but I didn't on the Iron Post, nearly a year later its still solid as a rock with nothing bubbling thru.
