Rust? What to do?

[Jim*]

Got some rust coming through on my offside rear arch it's only small but I know it's there!

What are my options with this?

Any advice is greatly appreciated!

Sand it down to bare metal. Put a layer of rust treatment on it before it gets re-sprayed.

This will stop it ever coming back?

as long as you get every bit of rust off the metal before applying treatment it should be good for at least another 10 years.

We used some rust treatment on my mates old datsun cherry about 8 years ago and its still mint.

after treatment has been applied u need to build up a few layers of primer befor you paint it.

I have heard a lot of good reviews about bilt hamber deox gel, but haven't used myself. It's also safe for paint work, so maybe

worth a shot? Have a read http://www.detailingworld.co.uk/forum/showthread.php?t=55949

I believe it's came from inside the arch and bubbling through so can't sand it back mate :/

I've just stripped down the rear 1/4 panel trims on mine and sprayed a load of waxoyl around the inner arches to prevent any future rust.

On yours, the rust may have got between the seam where the panel is tacked to the inner arch. Best thing would be to get all the rust cut out and repaired and spray some waxoyl around the inner arches.

Thanks mate! Sounds expensive though!

I've literally just done my rear arch and it's come up mint! I sanded it down with 1200 sandpaper making it smooth and made sure I got all the rust off then left some rush treatment on it for half hour, cleaned it off, panel wiped it down then set to primering it then gloss. Just had to sand down the over spray with 2000 wet and dry. Finished with a good polish and you would never know!!
