for those of you with steel tanks...

[LKunze]

Thanks for all the tips guys. All good options to consider. I've done a little research on the blasting as well and I guess that using a nutshell media is best for sandblasting tanks as it runs less risk of taking off too much steel. I guess when sandblasting with sand you have to be careful not to leave the gun on one spot for too long.
John, my corrosion on the tank is exactly as you described. It's only in the area where that damn boot covered the tank. I'm throwing those boots in the trash. > It is nice to be able to stand the tank up but since it causes corrosion I'm not using them anymore. The corrosion must not have been that serious as it did pass hydro and visual inspections a short while ago.
