There's obviously a lot of helpful information on rustproofing on the forum, but I haven't been able to find any photos to help provide a steer about drilling into box sections etc. I'm aware of the existing holes that can be used e.g. seat belt mounts and the cross member, but it would be helpful if anyone has any photos to show where to drill. Is drilling always necessary? For obvious reasons I would like to minimise the amount of drilling.
I haven't chosen a rust proofing product, but I do have access to an air compressor.
Any photos or links would be much appreciated.
Thanks!
