@100CRZR : the Woolwax application is kind of a one-time PITA. I used a shop that did a thorough rinse and Salts Gone, then letting it dry before undercoating. They can even handle some slightly more involved rust remediation. All-said, it was right about $1K but they were very thorough and Woolwax is a great product as confirmed by others here on 'Mud. They said touch-ups every 3-5 years is a good idea (depending on use) and run somewhere in the $300 range. To me, it's all a worthwhile expense to keep these rigs forever.
