Hello all I am new to this forum......
I have had my defender now for 5 years and last year i stripped back my rear cross member and then painted it with "Kurust" then an red oxide and undercoat and finally two coats of Smoothrite flat matt black.... A year on and the rust is back..  ..any ideas what I should do next?I dont really want to get it replaced as it isn't that bad yet...... |

Welcome...
Ku-Rust and most similar treatments will only acid treat rust on the very surface, it doesn't penetrate very well, you have to make sure you take the rust right back! I would get it right back to bare metal and do as you did before so the Ku-Rust will act on any surface rust pitting that isn't too deep. No need for red oxide and Ku-Rust though, Smoothrite will go straight over the Ku-Rust, the red oxide isn't doing anything in your case, (never does much anyway!  acid converting treatments will stop it dead, red oxide just slows it down and it will all have to be done again eventually as you found out!).
Could try Fertan next

it would probably be a good idea to strip all of the old paint off as well so go right down to the bare 'fresh' steel so there is no paint or rust left anywhere on the whole thing. For longevity maybe a clear coat / lacquer would help as of course and slight chip or knock into the paint to the steel will of course let the rust to get in and it will happen all over again. | iPints Member Since: 15 Jun 2012 Location: SC Posts: 294

Thank you both for very quick response.
I did bring the whole thing back to bare metal but I think the areas of rusting needed more work.....I will try again when we get some decent weather!! So maybe next year then.....  |

A grinder to start taking care not to take too much off or not to gouge it into the steel. And some sand fine sand paper to take out the imperfections Diesel$ Live$ Matter. ⛽️🛢️👨🔧🧰⚙️ RED, WHITE & BOOST! 🇬🇧 |
