Well, I got more questions

[GOPAPA]

What business is there out there that does sand blasting or what ever it takes to clean up the undercarriage of my truck.. it is dirty and rusted looking all over underneath .. I want to have a sprayed on undercoating when cleaned up. and then put the new cat and muffler and tail pipes on

Do places like muffler hut sand blast also ?
I can think of brake lines and all the open places under the motor that sandblasting wouldn't be good in those areas .
What are other things that should not be hit with a sandblaster
