Your first thing is to get a decent sized fan to blow all the rust dust out when youre down there.
Then you gatta get yourself a good n99 or p100 respirator. And i would go to town with a angle grinder and start grinding the rust away as best as you can. A wire wheel isnt going to do jack to that. You gatta grind that thick pitted rust off as best as you can.
I like the recommendation of a respirator but the grinding has me shaking my head.
A grinder doesn’t discriminate. It will remove rust and the precious metal at the same rate leaving you with a weaker frame than before. If sandblasting is not an option than a stiff twisted wire wheel and metal prep is a much better way to go.
Frame is 1/8 inch thick youre not going to remove much metal.
Just grind enough of the crusty rust off. The problem with wire wheel is they polish the metal.. including the rusty chunky metal and it leaves the chunky peices on there. Meaning chunky stuff you dont see will be polished but have rust underneeth it.
Trust me. Ive been dealing with rust for 4-5 years on my wagoneer 100x worse than yours. A wire wheel has its uses but only for the very light rust yours a bit deeper than that.
Im not saying to dig deep with the grinder.. just get it shiney. Takes only a second.
Like in my picture on my post. I linked. Do you see me grinding it down to paper ? No i just got it till its shiny and clean. The pitting you see deep down dont worry about with the grinder thats where you use the wire wheel. Just get the crusty stuff off with a grinder.
See this pic. This is my donor peice i was lining up to my frame. And see how i cleaned it up ? Just go up and down up and down with the grinder dont hold it in one spot forever.. itll grind the rust off and leave 99% of the good metal there.
But if youre too scared to do it. Then use a wirewheel.. its up to you. But as you can see i didnt make anything thin
