Cost to Sandblast a K-member

Tyler, STOP!
Before you do anything, please do a net search for "electrolytic rust removal" or something similar and become very familiar with the process. Here is a link to a good explanation: http://myweb.tiscali.co.uk/andyspatch/rust.htm
Pay special attention to the products used (washing SODA, not soap) and the proper electrical connections (VERY IMPORTANT).

The process does wonders when done properly.
