chysm60 Posted October 17, 2020 Share Posted October 17, 2020 This is the first time I have asked a question on this site, so I hope I have the right area to post this. I have a Simplicity 9518 4x4 diesel tractor that was made in 1983. I am in the process of installing new tires on the old rims. My question is this, My rims are rusty on the inside and I would like to make them smooth again without sanding the metal down too much. I would like to know if anyone knows of a product that I can use to make the metal smooth again before I install the tires and tubes. I plan on painting them after the metal is smooth to prevent them from rusting again. There must be a product out there that can handle the stress of a tire and tube that can be applied and sanded down. The metal isn't really too bad, but I don't want to take a chance that my tubes might be damaged during use. I plan on loading the tires after they are installed for weight. Also, does anyone know the paint number for these rims so I can paint the outside of the rims correctly? They are the off-white color. Thank you!

720nut Posted October 17, 2020 Share Posted October 17, 2020 Myself I'd just blast and paint them, Just my $.02 2 Quote Link to comment Share on other sites More sharing options...
Bill725 Posted October 17, 2020 Share Posted October 17, 2020 I suggest using paint with hardener in it or powder coat. FYI, spray can paint does not have hardener. 1 Quote Link to comment Share on other sites More sharing options...
spi Posted October 17, 2020 Share Posted October 17, 2020 would be worth the effort to sand as smooth as you can get it to save the tube. Quote Link to comment Share on other sites More sharing options...
Snojetter Posted October 17, 2020 Share Posted October 17, 2020 I had a very pitted rim where I used JB weld. Basically, I was looking for a filler that would result in a hard surface once it cured. I had the JB weld on hand, so rather than run to the store looking for something else, I used what was on my wall. Seems to have worked just fine. 1 Quote Link to comment Share on other sites More sharing options...
RAC Posted October 19, 2020 Share Posted October 19, 2020 Have them sandblasted and use body filler over epoxy primer. If badly pitted treat with ospho first. Then prime and paint. Don't powder coat something that's been rusted, it'll just rust under the powder coat. 2 Quote Link to comment Share on other sites More sharing options...
lugnard Posted October 22, 2020 Share Posted October 22, 2020 I have used Por15 on badly rusted rims with great success. For that stuff to work good tho it needs to be very rusty and don't clean it more than getting the loose rust off. Mine have been so bad I need to use a welding chipping hammer just to get the flakes off. Then a light swipe with a hand wire brush. Blow them off with air and brush on 2 coats of por15. Sets up rock hard and will smooth out the pits. Some people have trouble with it but I feel they are cleaning rusty surfaces too much, It needs to "bite" in to something. If you do get some be very careful to keep the rim of the can free of paint or when you go to get the lid off again....you won't be able to!!! I also store it in the fridge and it lasts a long time.

AC716 Posted October 23, 2020 Share Posted October 23, 2020 Once you knock off the big rust use a rust converter, to keep the rust from reforming under the paint. Then prime and paint. 2 Quote Link to comment Share on other sites More sharing options...
MrSteele Posted November 6, 2020 Share Posted November 6, 2020 I would sandblast, fill any really bad pits with body filler like Bondo, then paint with a good rust preventative primer like a brush on Rustoleum. If you are still worried about your tube, do what farmers did in the old days, put a liner between the tube and wheel. That liner can be, and usually was, an old tube cut in half with the valve stem cut off. Cut the tube to cover the wheel from bead to bead across the wheel. Now, your tube is resting on rubber instead of the steel wheel. 2 Quote Link to comment Share on other sites More sharing options...
