I have done a lot of the structural repair (new floor largely in place) of my Olds, however the car has a lot of rust in really hard to reach areas (thinking that blasting will be tough) like behind the dash and in the cowl vents. It's all surface rust for the most part, however, I want it gone and want any rust I can't currently see to be gone as well. So, Is having a car dipped a good way to go? Or should I stick to finding someone in my area who can blast it (seems like that's the "tried and true" method)? I'm worried blasting won't get all the rust from the nether regions of this car and it'll come back to haunt me later. Thanks in advance!
