you can cut and weld yourself although you will have to take the welding slowly and with short welds to stop the panel warping. and not to mention its best to grind down the welds. you might as well leave it to the pros to do it mate as they have to fill the panel over make it nice and smooth and look straight then primer, flat down and paint whole rear quarter with a possible blend in on the door

will practise on a scrap wing or something first , cutting it and rejoining it make sure all my welds etc are ok and will hold :) will then consider giving it ago on my car! even if i did the painting its going to look better than it did now. i was thinking of just cutting the arch out and welding the arch in and not half of the rear quarter, would this be ok ? i know it might make blending the paint in a bit more harder etc but rather that than cut half the car out and the whole panel having a diy paint jobbie

Wheel arches are repair panel you can cut them to the size you want, As for quater panel cut out the corroded area goin about an inch past the rust once you've cut that out and cleaned it up with a grinder,trim repair panel to fit but where your goin to weld insert it underneath (not over top and weld it will make it sit proud and harder to repair) best thing to remember with a mig is make sure metal is really clean and apply a zinc primer yeh just spot welds will be fine as this way you won't put to much heat into it and distort it once you've done that and ground welds down you could use a glass fibre paste such as p40 to bridge over welds rub that down then shape with normal filler,then apply an etch primer and high build primer as necessary,depending on colour of your car you may need to blend rear door..

 

What colour is your escort is it noveau red metallic as I think I've got some of that in my shed left over from my old escort which is solvent basecoat don't know how close you are to Essex??

ive never done a panel before myself, Andy how do you mean weld underneath? I always thought you cut the panel to the same shape and effectively but welded them together?

Yeh you can do it that way if you like just means that you have to trim it to fit exactly with no gap,what I mean is once you've cut your arch on your car trim the repair panel to fit but where you have cut it to weld it insert arch your goin to weld in underneath it that way you have no gaps and something to weld to (harder to fill a gap in with weld if you've never done it before)

 

Or if you want to try it there are now panel bonding adhesives which are meant to be as strong as welding that way you could just grind rust of and panel bond realist panel on leave over night then do filler next day but as it's been put over top you to over fill as it's been put on over top and will sit proud a little bit

 

The mercedes quarter panels we do at work are all bonded on with rivets as well no mig or spot welding same with BMW as well sounds strange but it's merc,bmw approved

Yeah colour is pepper red pearl...

 

i also dont get the " do it behind " thing?

Pepper red met and noveau red met looks similar colour but noveau is slightly darker (I can check colour codes at wk tomorrow unless you know for definate yours is pepper red)

 

Behind is where you cut the arch on your car insert new wheel arch behind it (underneath) like issue I have seen these put over the top and welded bit you will end up filling a larger area to get filled to blend in

 

Was gona say if paint is right colur you could have it as it's just gona sit there some one mite as well make use of it if I can find it lol

 

Thing with painting metallic is to apply wet coats till it's covered (not to wet so it runs) letting it dry between coats then the final coat (known as drop coat) is a dry misty coat to make metallic sit even

right yeah i see so you overlap at the back slightly to bring the gap in a bit more so you let the repair area over hang a little at the back , and then weld at the front to join the arch and the rear pannel together ? its only my arch need doing , i think the inner arch is a bit rusty , what its like up a bit futher when i cut out the arch i dont know. once its welded over on the overlap between the two pannels , what do you do with it at the back of the pannels ? as dont want nothing sticking out sharp etc would like it nice and flat , also whats best to "seal " the repair from moisture etc

 

and in all honestly ive never welded before propperly lol ive had little plays on random bits of metal and thats about it , would i be up to the job ? it cant be that bad surely , just to stick a butt weld on , along the pannel?

 

and whats the best way to cut and mark out the repair pannel to cut it out to the right size , is it best to cut with grinder or hand tools ?

 

on mine it needs a bit of repair panel by the door shuts too where the arch pannel goes into the door

There not that hard to do,best thing to cut it with would an air hack saw if you don't have one or access to a compressor you could make do with tin snips just the wheel arch lip is spot welded so you will need to drill these out there like faint circles in the metal, there isn't alot behind behind them...

 

For the inside I would TIGER SEAL it's a really good sealer you can brush it on to seal back of arch once it's dry (left overnite) then apply WAXOYL...

 

Welding is fairly simple but remember the cleaner the metal the easier it will be to weld don't see any reason why you couldn't do it as long as you feel confident doin it also use a decent welding shield as you wouldn't want to get ARC EYE from welding your eyes will be very sore and if it's bad you won't be able to bear daylight on them

 

Also disconnect battery on your car when welding unless you have a surge protector to put on battery this will stop it power surging and ruining electrics on your car

 

All you need is tack welds if you seam weld it that just put alot of heat into it and distort the panel

 

Feel free to ask any questions or any more advice you mite need
