I have some moisture underneath the trunk lining. Surface rust pretty much. Anyone ever use Rhino lining (used for pickup truck beds) to protect from water?
When I had my 67 Galaxie restored, I had the trunk and underneath coated with rhino lining. Works great. If you are getting moisture under your trunk lining, maybe your trunk seal leaks. I'd remove the trunk liner until you do something. UticaGeoff
The trunk seals may be fine, it could be the gutter for the convertible top has rusted and is leaking. That is my problem. I found a clean on out of New Mexico for my Wildcat. Good luck, you want to make sure that you have no leaks before finishing the trunk floor. You don't want to do it twice. Steve
I used a black, rubberized, water proof rocker guard material that was applied with a 'shutz' gun - very clean finish similar to the rhino guard truck box finish, but not as thick or solid, and maybe a little easier to apply. :TU:
When I lifted up the trunk mat/liner, I found some moisture. Pretty much surface rust. I wiped it down and aired it out. I decided to coat the trunk with Por-15. I'll let you know how it goes.
Its most likely condensation.. inside the truck is cool and dark. I dont put that rubber mat in there... I remove all possibilities of water/moisture inside the car.
As stated, POR-15 works great. Just don't let it dry on your skin. It's own solvent will not remove it. Toss the rubber gloves that they send with it and use good ones!
I had the privilege of judging a few classes at the Nats last Oct. In the Stock GS class 5 of the 7 cars I looked at had some rust under the trunk liner. The owners didnt even know it was there. One of them stated that they had just re finished the trunk a few weeks before the event.
Yep, I think the trunk mat material attracts moisture. The guy I purchased my Pontiac from sad that when he put the car in the garage 30 years ago the trunk had some surface rust. Today the trunk floor is completely rusted away. The prior owner said that the trunk never got wet and he couldn't believe the rust when we pulled everything out of the trunk and lifted the mat.
It's not that it "attracts" moisture - what happens as metal heats and cools is that condensation will form on the surface, and if the rubber mat traps it then the moisture will rust out the metal. You really either need a 100% vapor-proof barrier (like Rhino-liner or paint), or just uncover the metal and let any condensation evaporate. I've thought about rhino-liner for a trunk too. I'm getting a new trunk floor put into my '73 Lesabre as we speak, and I was thinking of painting it but maybe I will get it rhino-lined... -BC
All the condensation, which created rust, in the gas tank over the years created a few pinholes. The tank was removed (bolts were stripped so had to use hand tools to get it our, cause risk of sparks), cleaned out and repaired.
We just had the trunk floor re-done in our '73 LeSabre with all new sheetmetal, so I've been very intrigued by the concept. It seems that the success or failure of bedliners has a LOT to do with the installer. The liners themselves are fine, but it is easy to rush the installation job. Anyhow, it looks like we will go the POR-15 route in our new trunk.
If the material you use is bonded to the panel..it wont sweat/rust por15 and their chassis paint or spectrum/firewall/lizard skin wont rust Prep work effects final results and longterm durability
Yes, but many of us apply it over one of the rust preventing products mentioned. If I'm using a light colored spatter paint over a dark rust inhibitor/preventer, I apply a coat of light gray paint, or primer, first. Gives the right color base so you use less of the more expensive spatter to get coverage. I also apply it when the POR15 is a bit tacky so adhesion is better.
