Is this a good method for a truck that wont be being restored? I heard it gets into berings and such...It is suposed to mess alot of things up..I dont have much pitted rust except for in the bed on the side under the part that hangs over on the top of the bed....everything else isnt to bad...should I have them sandblast it or sand everything or sand blast just the pitted part and sand everything else...

Tell me everything there is to know about sandblasting would be great!! thanks
