Well, after tearing apart the suspension on my daily driver Accord I've decided to take it one step further and rust proof most of the car. My plans were to rust proof the inner fenders and wheel wells, underneath the rocker panels, and on the underbody. I've used a few rubberized undercoatings that were ok, but they didn't hold up very well at all to rock chips or cleaners like brake clean. I started thinking something more along the lines of truck bedliner or rhino liner because this would hold up very well to rock chips and be nearly waterproof and rustproof as long as you did it right. Something roll-on would be nice because if it's easier application, but spray on would work also. Do you guys have any suggestions for brands or something else to use?

 

if you want to rust proof the entire car, my suggestion would be to take a rag with some brake cleaner/laquer thinner to every area that already has undercoating on it. try to get as much off as you can and then start fresh with a roll on coating if you wanted to go that route. they have that stuff pretty much everywhere you can get rubber undercoating.

if i were to do the same thing, i would rough the clean surface with something super aggressive like 40-80 grit first. then roll on the truckbed coating. after the truck coating dries, i would put on a good thick layer of rubberized undercoating. it may seem like overkill, but then you won't hear every little pebble and piece of road debris hitting the wheel wells. rubber undercoating is pretty soft and helps with noise a bit. then, if brake cleaner or whatever gets on the undercoating, it will just expose the truck,bed coating a bit but you won't notice it.

 

In the areas I'm putting it I don't think I should have a problem with getting more noise from rocks and such. I'm kinda thinking of using both a roll/brush on and a spray on bedliner so I can reach all the areas I need to get into. POR-15 is also something I'm kinda looking at also.

 

for them to hold up well try to brush clean,washout dirts.let it air dry.then apply the protective undercoating.cause if u spray over the dirt it will still build rust.like gsr said.

Yea, of course I plan to clean everything up very good before spraying or rolling anything on. More than likely I'll scuff things up a little before applying the bedliner to get it a good surface to stick to.
