Thanks for the input members .
My tops have sat outside my shop over 2 years i have owned them . Then the whole sheet was out for a bit . So i dont have basic level flash or surface rust .
I have tried 40grit flap wheel and course twisted wire wheel cone and it just buffs the rust . So this is why i planned on blasting . He will use recycled media that wont be as course to make the surface as ruff .
When i get them back if i need i can d.a. sand the tops down a bit to kill the highs off the surface .
I have a heated shop at 55* to maintain temp and keep humidity out . Then wood stove for main heat . The rust is not a major problem . And i didnt plan on painting these as there work benches not fancey works of art .
Again thanks and i will keep you posted with before and after pics .
