Any luck with Rust Converters or OSHPO?

For combating rust, has anyone used OSPHO or other "rust converters"? After scraping, brushing, and sanding I have used the OSPHO on a few things and it seems to stop rust and takes paint well. My question is should I use it on implements or tractors in place of sand blasting.

Thanks,
Charles

Charles I have been using rustoleum rust converter for years. as long as you keep it in it's place it works great. You must clean the surface fairly well but not to the point of sand blasting. any loose rust will be harboring moisture so you will get rust pushing the coating up in a year or two. I use it mainly to hold the advance of rust on something that I know I won't be able to do a real good job on for awhile. If you have a surface that has gotten pitted by rust it's doubtful that you will get them clean enough to keep them from bubbling up unless you sand blast.

Thank you SHOWCROP. I have found if you wire brush till the oxidized metal "shines" it takes OSPHO well. I have not uesd it enough to have long term results. I plan to use it on my Mott flail mower and JD brush cutter deck. Directions say that priming is not required... I thought it was always required.

Thanks again,
Charles
