ALRIGHT! Finally got the frame and engine crossmember blasted.
Cost me $300 at A to Z Soda Blasting in Justin, TX. Very nice guys, great to deal with. They said they were using some kind of mineral stuff to blast, not soda. I told them I didn't care as long as it came clean!
First pic: dirty nasty frame
Second pic: blasted
Third pic: after a couple coats of POR-15, luckily my 13 year old daughter helped me. What a pain!
