When fixing rust holes like this, the damage is always bigger than you can see. Plan on welding in small patch panels rather than trying to fill in pin holes. The small pin holes will become big holes when you start burning off the thin rusted metal you can't see.

Most of these areas can be covered with seal sealer so perfect butt welds of the patch panels is not necessary. Definitely treat the rust inside so it don't come back.

Be sure to cover your windows with a welding blanket or plywood when you are welding the top of the cab and drip rail.

I didn't and it ruined my glass from the hot bits of slag that falls down and hits the glass. The molten slag small bits will burn and pit the glass.

My windshield was already bad, but it ruined my side and vent windows which were factory tinted and had to be replaced.
