Using a hammer the paint will come off on the out side of the wing and will rust but won't be see but still rust on a good body is not good rely.if you mark where its rubbing and then you have a idea on rolling or cutting just that bit. And before you go mad make sure you can still get fixing in the plastic arch.have a can of spray handy or you can cut the inner wing higher than the outer wing and still cut the outer wing, but put a LITTLE bit of expanding foam in the arch to seal it and fold/bend the outer wing over the inner before the foam goes off and still roll it but you will have to have can of spray handy again and mark where the arch sits on the wing and where the fixing points are before you go mad with the cutting....

I didnt have any trouble with split paint, but if you did just give it a quick coat of primer and paint. doesnt even have to be the same colour if using the arch trim as it will cover it anyway.

My arches are held on fine with the rivets that are left, you only loose 1 or 2 rivet holes. You dont have to go mad and hammer the entire lip, just the bit at the top above the wheel!

did mine with a grinder. took off the entire lip around top half of wheel.
70mm with ET20 and no more rubbing

100mm, et30, 185/60/14, no rubbing.  I started off using a borrowed roller, but gave up and beat the lip with a hammer instead... much more effective!   

I also still managed to retain enough rivets to hold the arches on without any sort of sealant.  The front arch-liners got ditched tho, I covered the inner arch with spray-on underseal instead. 

The worst part of the job is scraping sealant off the rear lips, which will enable you to really fold em up flat.  Screwdriver+heatgun+stanley knife was my method of choice, took ages, but is worth doing before jumping in with the hammer.

And also once beaten/during beating into shape, get some paint and spray-on underseal onto the affected areas... touch wood, theres no sign of rusting on mine yet... 

Remember on the rear-left you shouldn't just do 10o'clock to 2o'clock; more like 8o'clock to 2o'clock... because as the car is lowered, the rear beam causes the rear wheels to shift towards the front of the car... if ya know what I mean?
