rust on frame

I just purchased a 1998 4x4 tacoma. it is a standard cab with a i4 5speed.
It was not till i washed off the dirt that i saw a lot of surface rust on the frame.
It seems to be everywhere.
It does not appear to be deep, rust.
Almost like sandpaper would take it off.
maybe undercoating?

I think i should do something?

any suggestions

 

Yeah i went under my truck and sanded all the rust down and painted it with a special rust neutralizer. it isnt hard to do and can save you a lot of money in the long run. I woulddefinitely do it if you have the free time to do it.

 

take it to the dealership ad have it tested. 1st gen toyotas have frame rust issues, use the search button up at the top right and look up some stuff on TW

And welcome
