Question for you guys, I REALLY need to redo my Ranch Hand Guard (its a Full guard with the front receiver type) its rusting/peeling bad. I plan on using a Cherry Picker to hold it while redoing it. Here is my question. I plan on sand blasting it all down to the metal, what is the best and cheapest rhino liner type spray on to use and how much do I need? I have a
gravity fed spray gun. and do I need to primer/etch it even though its down to bare metal if using a rhino lining....I'm thinking Herculiner.. Thoughts
