Rust removal(surface rust under paint)

[Thommo]

Hi all, new member here (without a SM or PV but joined up in the hopes of finding one)
Ne who, maybe one of the panel beaters/ spray painters can help me out.
Ive started work on my (dirty word sorry) Ford (xy wagon)
My Question is, Ive started to remove some old paint in the engine bay, and while removing some crows feet ive noticed some surface rust hiding under some old paint just wondering what is the best way to remove, treat, repaint??? As its mainly where the battrey tray sits so want to do it right to save more work down the line, Any help would be great.

Thanks Thommo

gday Thommo you'll need to whip off all the old paint (paint stripper with a scraper, large buff with 40 grit pad, sandblasting etc) ALL the way to metal in order to access/remove all rust. treat rust and then etch primer, prime/filler primer and then paint. Might be worth getting your local sandblaster to do the battery tray. should be cheap and its easy to remove id imagine

Its a massive pain in the ass but it has to go back to metal if you want to do it right. the paint wholesaler i use reckon they have a good sealing product but im yet to try it
