Undercoating?

[GM15SierraAT]

I have a 2015 GMC Sierra All-Terrain.  My underbody is rough looking and a few spots have early onset rust.  I like to keep the truck clean and want the underbody to look new again and prevent rust down the road.  I keep my vehicles for a long time. I've talked with Line-X, Ziebarts and the local detail shop who just uses 3M undercoating spray.  I've been researching this as well and keep getting mixed reviews.

 

What's everyones opinion?

 

Thanks!

I plan on cleaning the old stuff off and using an epoxy frame paint

Im taking my truck in tomorrow for the tsb on the frame rust. I have spots all over my 2017 frame and am curious to see just how thorough of a job they do with two different spray on chemicals. And at a dealer that doesnt have an autobody department. If your under 60k I think you still qualify for the rust warranty.
