spots of rust appearing on rear arches SEC

[arfan786]

hi guys

i am in a dilemma my car is in the body shop right now having the gen 2 amg rear bumper and side skirts along with AMG lip spoiler.

The bodyshop have said best to do the arches now while bumper and skirts are off and have been quoted 250 each side?? is that right? also the rust bubbles are very small on each rear arch if i am honest not very noticeable.

I was thinking of the costs going up and the rust isn't spreading i am unsure whether to do it now as it may cost more to do it later and also will i require replacement arches etc or do i just cut them back etc?

any ideas

"AMG" is the route to higher prices.........

I've been quoted the same amount for my arches.

They don't really need replacement arches if i am honest. I am just being a bit extra i might wait a bit and see how it goes.

Depends on the extent of the rust and what they propose to do for the £250. If its a cosmetic cover up job then £250 a side is pricey for what you get in the long term . If its proper metal work replacement then it merits serious consideration as a long term repair. Be aware that sometimes rear wheel arches can rust from the inside as a result of the classic rear window/parcel shelf leak allowing water to accumulate in the rear boot side wells. If this is the case that problem needs addressing too for long term rust prevention. Sometimes embarking on this type of work can require a lot of work.

i have had all that checked out when i bought the car as i did have a small leak in boot in the side wells and that was repaired by the SL SHOP. however the arches are not too bad at the moment if im honest.

I would be inclined to spend some of the money on a good underbody clean and anti rust treatment. Rust prevention and restoration | Frost Auto Restoration Techniques

Once rust comes through its usually a damage limitation exercise- you will never eliminate it completely without using fresh metal. The £ 250 a side will be the cost of blending in a complete panel with the rest of the car. What colour is your car? Darker colours on small inconspicuous surfaces are a potential DIY-- lighter metallics on large panels best left to the pros
