Must look out for an industrial sized bucket of isopon when I'm at the autojumble this sunday as I think I'm going to need it judging by these pictures. Don't you love the way the previous owner has strategically placed the STP sticker to completely obscure the rust hole from my view?! Until it broke out that is.

The arch is pretty bad too, but hopefully TJM will be able to source me a replacement set. P38 will do until the summer and hopefully stop the rust spreading.

P38 won't stop rust spreading - you need to get some hammerite rust beater on it before filling. I used to use comma stop rust but they stopped making that. B*st*rds, it was twice as good as the hammerite stuff.

grind out any rusty metal until you have just strong metal remaining. Then paint everything with 'kurust' you can get it from halfords. Then prime over the top of that with zinc based primer. THEN fill with P38 but not flush to the paintwork, then fill the small amount left with P40, sand, then more zinc oxide primers, then paint. will look as good as new (for about 18 months anyway!.

:P :P :P

The biggest problem is that I have no access to power tools, welding gear or any sort of cover so its tricky to carry out satisfactory repairs. I have wire brushed it in the past, kurusted it and painted it with red oxide. My flatmate has the right idea, his metro has much more rust than the chevette. The back arches are like swiss cheese, so he kurusted the whole thing and slapped about two tubs of fibreglass over the whole arches. Honestly, the back arches sit proud of the bodywork by about half an inch - at least it doesn't rust though.

Tim, do you reckon a zip wheel in a drill would have the same effect as a grinder, or is this the kind of thing you were meaning? As I say I have no skills/knowledge when it comes to bodywork so its probably best left to the professionals - but that costs money. All I really want to do is carry out a reasonable looking repair to get her through the winter until I get some money and can have it properly fixed with new arches.

While I'm on the subject, there was a pinhole of surface rust on the drivers wing about six months ago. I rubbed it back, kurusted it and put a little skim of P38 on to fill the tiny hole, then a couple of coats of red primer followed by a few coats of Henna red. Cut it back and polished it, was very impressed with the colour match. However recently I have noticed the whole area (about the size of a 2p) has bubbled up again and is starting to break out. Planning to have a day of bodywork - what's the best way to prevent this breaking out again?! I know new wings are a pig to get hold of and mine are in very very good shape otherwise, so I want to look after them.

ok first off a zip disc in a drill will do fine, but be VERY CAREFUL

firstly, if the disc slips or catches and your hand gets jrked, you might have a nice scratched line up your arch


secondly, with the wing, have you considerd that a tiny area of rust may have remained untreated at the far side of the wing. you need to get at both sides ideally. Rust is a deveil and you can never truly get rid fo it forever without starting with new panels. the trick with getting a smooth filler is not leaving it to harden overnight before sanding, and starting with a coarse base and build up to a finer filler. then sand this down flush to the paintwork. I'm crap with bodywork myself, but I have a mate who's gifted with it. My arches are filled and you honestly cant tell the difference. rust hasnt returned either


another problem i've just spotted s the proximity of the rusted metal to the outside of the arch, if you arent careful you'll lose all the metal off the outside and you wont have anything to build filler to. these ones may have rustd a tiny bit to far. try it, if it dosnt work or goes pear shaped by the new arches of TJ and use the astra til they arrive!

the pin hole on the outside was a big blister on the other side. i would start thinking about a grp wing, as Tim says, you can't get rid of rust, real pain.

on the rear arches and the door i think your going to need some mesh to bridge the gap. if the edge of the arch does come off you're going to have to get all artistic and model them back in.

Tripe. My front wings are liberally undersealed from the inside and I don't fancy trying to get that stuff off to effect a repair. Although I did have a really good poke round inside with a headtorch and a small hammer to check for any weakened areas and didn't find any. As long as the bubble isn't through then I'm ok.

TJM has sourced a set of arches for me so when I have money again I'll get someone to put them on for me. Anyone have any ideas how much a job like that would cost, including spraying them?

tripe TRIPE

onions to you i say!

risk is if there is water in the bubble, if it's dry it should be ok, if it's wet it will perforate.

no idea how hard the replacemnet job is, mine came ready done, sad since they will be cut off! i guess the hard bit is joining the new outer to the old inner.

I meant tripe as in blast, bugger, nuts, rats, fook, ar$e, jobbies. I wasn't doubting what the guys were telling me, just acknowledging the fact that a job I thought was small and simple has got a bit bigger. I'm a man with a disintegrating car! *sobs*

The bubble appeared dry until I applied gentle pressure and it squirted at me. Since then I have noticed nice brown spots appearing on the paintwork under it - guess I need to get that sorted asap then. Monday it is if its in any way dry!

holy rusted metal batman! you'll have to peel all that underseal off and sand bacl all that bubble right back to the original metal so as to leave nowhere for any water to hide. wing will have to come off obviously to let you get to eh job properly

Its also almost 100 quid a wing. Pish. Think I'll take the wing off the car and bring it into the flat in the hope of creating a dry environment in which to effect a decent repair. Lot of work to be done then *sigh*.

hm true
and the gbh of the earhole from the other half

priceless!

i have a similar problem, a pair of brand new unpainted wings came with the new shell, they just have some surface rust. i'm debating having them sand blasted and using them or selling them and using some grp ones.

Does grp stand for genuine replacement part as in vauxhall ones or is it something else? 'glass resin polymer? gold rendered paintwork? gladly released product? gay repressed parrot (he wears bright colours and is made to suffer for it).

Thankfully I live in a flat with two other tolerant souls who are sympathetic to my affliction. I'm planning to put it in the bath! My bedroom is only 10x6 and it already has the aforementioned wardrobe in it so space is a little tight. I just don't want to come out some morning (not like the gay parrot anyway) and find the wing with a rusty hole in it.

i had a mate who rebuilt his sunbeam rally engine on the dining room floor of the 15th floor flat he shared with 2 other hairy Scotsmen. certainly added an interesting smell to the premises.
