Rust - VW Polo '99

SJPK

Right, so I bought a polo off a relation that needs a few bits done to it (that I know of...) The bits of main concern to me is the rust. It seems to be 'deep surface rust' if theres such a thing? Thinkin of sanding down with angle grinder, filling and painting, will this be sufficient :-D
Also, the bottom half of the bumper was rusted beyond repair so i took it off and have struggled to find a replacement, any ideas?
On the phone atm, will add photos...

Those steel lower bumper sections are available from Somora so any motor factors should be able to get you one for small money. The front one is around €35 and the rear around €70.

To be honest I'm trying to keep costs to the bare minimum and keep tryin the scrapyards the oddtime

Here's a few of them pictures

And in its current state :-( :-D

An ex of mine had a Polo of that vintage and at the time I did a bit of checking on the rust spots they were prone to and they were not few in number. Higher than average from what I could see. IIRC there was an issue with seals, the boot being one and another on the doors.

My worry would be the sill rust you have. I've found rust is like an iceberg, the bit you can see is usually only a small proportion of what's actually there. If that's the case your sills do not look too sweet and they're structural. And that might be an NCT failure.

I'd break out the wire brush and dettol sandpaper and take down the rust until you get to good steel. That'll tell you the real extent of the problem. If it's mostly surface then treat the area with a good rust treatment/killer(not your usual Halfords crap, try for dinitrol, bilt hamber or similar). Then hit it would a decent zinc based primer. Then top coat. Then hit the sills and arches with some anti rust wax. Waxoyl is ok if you're stuck, but again Dinitrol and Bilt Hamber are soooo much better.
