I didnt find it messy in the least,just scrape it off and throw it away.The frame rails are pretty open,just use an air gun to blast it out.The inside is a whole other story,after doing a complete inside blast you will find sand/media coming from places you never knew where there,but the peace of mind of having bare clean metal far out weighs the nuisance.Just spend EXTRA time with an air gun for the inside and when you think you got it all out............Do it again and again,lol
