Ok well I plan on spraying bedliner on the inside of my tub this so im , in a way, pre-prepping the cabin. Making I can get all bolts loose and such. Then I come to the drivers seat...what a stupid design... the 2 bolts on the underside and rusted to sheit and the threads are gone. And it looks like they are connected to the seat bracket. Sooooo anybody have any tricks that work? If not then ill just leave it in there and spray under it lol.
Get some small water balloons. Fill them with CLR and put them on the bolts. Try to get the mouth of the balloon around the nuts. Let is sit for a couple days like the. The CLR will loosen the rust. Then take a die and run it up the bolt as far as possible to clean the exposed threads.
