Undercoating? - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Last question because I need to get to bed.

I have always heard that undercoating was something that the salesman try and sell you as you sign on the dotted line, and to stay away.

However, I watched an episode of Musclecar on t.v. the other day and they were applying some to one of their projects. It looked kind of like Rhino liner.

What is the general opinion on this stuff?

bad idea, all under body parts are coated and treated to withstand road chemicals, so you don't need any of that crap

If I lived up north and planned on driving it in the snow on salty roads, I'd contemplate it. But, living in the south, it's a waste of money.

Rhino lining is some bad @ss stuff...and does a lot to protect (so I'm told). Rhino lining also adds a few pounds.

Even up here, it's a farce.
The doors will start to rust out before the underbody...and this coating does nothing to protect that...

I would add that if you REALLY felt this was necessary, you are better off getting it done at a shop that specializes in this type of thing.

If applied correctly....its good stuff. I have a 48 Chevy Panel truck that was undercoated when it was new. I had to scrape that stuff off and underneath it the metal was still like new. Only problem is...if its not applied correctly and completely water can get trapped behind it and create huge problems.
There is some new stuff called Lizard Skin that is a spray-on ceramic insulation/sound deadener. Its some good stuff. I'm doing the paperwork now to be able to buy it wholesale. I'm going to use it on my 69 Camaro instead of DynaMat.

Such as Ziebarting.

My dad use to get Ziebarting on all of our family cars its pretty decent stuff... now my family has all saturns from back when they were all plastic so its no real big concern 'cept for a couple o'spots... if your just gonna drive your car on nice days though it really isn't worth it...

Just make sure the drain holes at the bottom of the doors stay open.

That is a good point. You definately want water to drain out where it was intended.

The theory is sound. The problem is if it doesn't cover every inch of metal, then there can be rust. So there's no margin for error, if you get any rust, then it didn't do what it was supposed to, in other words it was a waste of money.

*radz28* · 01-21-2009, 02:20 PM

I believe the floor is at least galvanized on the under-side, if not on both sides. Even still, if they are asking a lot of money, I'd find out exactly what they're doing and make sure there's a warranty or something that will justify the price. If you're only keeping the car for a few years it's not likely to be worth it, but if you're in it for the long haul, it may not be a bad option if funds permit. I don't think it will do much to protect, though, unless every square inch of sheetmetal is treated though, just like was already posted. And if you think about it, you'd have to remove EVERY single part from off the undercarriage of the car, and I just don't see that happening.

If you're that worried, add some undercoating to the wheelwells and call it good. Some will help with noise and protect against chips. I don't really think it'll be worth it though.

I live in Florida right on the coast. My friend at work gets a paint sealant every six months. They say if you don't do that it will rust quickly here. Does that sound right?

djinva · 01-21-2009, 02:40 PM

1.I would stay away from it. I have seen it hold moisture which actually promotes rust.
2. It has a lot of markup which is money you could spend on something else.
3 I hate to see a car with undercoating overspray on the innerfenders, I like my innerfenders nice and smooth and clean.

Just my opinion.
