In the process of trying to repaint my jeep and sort any rust, I have noticed the entire underneath - body & chassis has been undersealed some time ago.
This has split/cracked in places creating a water trap and causing rust with the underseal just flaking off.
At the moment the underseal seems to be doing more harm than good.
Should the under body even be undersealed?
Am I best removing the underseal, sorting any rust, prime , paint and then treat with waxoyl or
Is it best to remove the old then re underseal ?
Any advice greatly appreciated
