The holes are for you to watch the rust form on the inside as well as out. You can get an endoscope to se it spread close up:I
I was painting wax-oil on to the underside of the Mini one day and my daughters ex boyfriend (dick head) asked why I was spreading bacon fat under the car. He didn't last long after that - thank God
Bacon fat!!! why hasnt that ever occurred to me before, when your working on the car and a bit of something falls of into your mouth it will taste nice and if your working into the wee short hours and get peckish you can lick the bottom of the car to keep you going, im not thinking of the rust proofing side of it just my stomach
I'd rather have a bottle in front of me than a frontal labottomy!
