Me and a friend would like to look into adding some undercoating/rust protection on our older trucks and would like some experiences and product recommendations. Our chassis are in pretty good condition, just some surface rust that we would like to inhibit and to protect from future offroad runs.
There's a whole whack of products available, but I would like to buy locally if possible, unless it's worthwhile even with the shipping costs.
We would probably just scrape off the old rust with a wire brush, de-grease + clean, then apply the product either with a spray gun or roll on (product dependent).
Any product recommendations and experiences? What kind of cost can we expect?
Thanks!
