Just bought a pair of rear wheelarches for my car as it's the only thing letting the old girl down (very rusty with paint bubbling underneath) .
Now i was wondering do i just weld in the new arches over the top of the old ones or cut out the old first then fit the new ones.
I was going to grind back the old arch and weld the new one ontop of the old one then let the bodyshop do the rest of the work I.E. fill paint etc etc.,is there any problems with doing this ???
what would you do????
