Rust starting on quarter panels

[massivespl]

so I live In Michigan and she's an old girl. 2002. Like two years ago rust was starting and I took it to thelen dealership and had them fix it. Well not even a year later it was bubbling and they suck at what they do. This winter has taken a toll on only the rear quarter panels. I'm not interested in paying a shop $800+ to cut out the corner and patch a replacement and paint it... I was thinking of just putting something like this over it. They don't make one for a 2002 Tahoe but I'm sure I can fab the 2007 Silverado kit to fit my Tahoe. Thoughts?

Honestly it's a horrible idea if you look closely at that picture it's already starting to rust on it. Plastic body cladding like that will only accelerate your issue. It traps dirt/mud debris and moisture and is almost impossible to clean behind it without removing it every time. If it's only starting to bubble a little after a piss poor repair it probably just bubbling from moisture and light surface rust. Take it to a legitimate body shop and have it looked at. If you want to fix it yourself and your handy and patient I suggest stripping it down removing any visible rust. Then coat it with a rust inhibitor primer a non glossy top coat to seal it then coat the bottom edge in a high grade bed liner or just pastidip. It will give it a sleek 2 tone look if you take your time and tape things off to give them a nice solid straight line.

Don't cover it up. Either leave it or fix it right

I have a rust problem that is more a surface patina on my hood and roof. I'm going to hit it with this product and a gloss topcoat they sell after I wire brush/palm sand. Luckily, my truck is a work truck so I'm not as concerned about how it looks finished.

I would sand it down and prime it and then put the Rock gaurd down so I don't have to paint.... It's not like I'm just going to throw it right on top the rust.

Do exactly what drakon543 said.sand it all the way to bare metal. Apply rust inhibitor. Then primer and adhesion promoter. From there spray base and clear yourself or send to a shop and have them shoot it for couple hundred bucks.
I personally would take it back to the dealership with a attitude that would scare those grown men into little boys. But that's me

I was told by a bodyshop that it is ok to just completely sand the rust off and no need to go to bare metal. Using less than 320 grit can cause scratches in the surface also.
