yeah thought so.
Most body works will hammer the lip over. Go see Marty, then if the paint cracks then take it to a bodyworks.
I did the guards on my stagea not long ago, as long as you heat the paint slowly and to the right temp, then you have a better chance of it not cracking with newer paint.
The paint on my 32 gts-t cracked, although Ben did them.
You wont be able to push the guards correctly with a guard roller, you'll more than likely strip the threads on the roller. Try using a bottle jack and blocks to push the guard.
