I have two or three pinholes in my driver and passenger floor pans. I was thinking of cutting out and welding in new sections but, came across this product from POR-15.

The question is, has anyone used this stuff and what have the results looked like?

The reason I am looking at doing this is because the underside of the pans look perfect and I would hate to create weld seems that would be visible from the bottom of the car. Just to clarify, the structure of the pans are very strong and not worn thin only a few pinholes.

Thanks

I had exactly the same problem, I used the POR-15 and it worked great.
LOTS OF PREP! POR-15 has to be done exactly as the directions say.



TIP: Use foam earplugs in the seat belt and seat bolt holes to ensure the POR does not seep in.

 

I like the por-15 also. It dries very hard and stops the rust. If there are only pinholes you might be ok. But usually the metal around the pinholes is very weak also. Post a pic of the floor.

 

Guys,

I think for the money and the fact that the product has very good reviews I will give it a try. Here is a picture of the current floors. I will wire wheel the entire floor first to ensure that no further flaking is present.

thanks

Picture attached....

 

Where there are pinholes there is thin metal. POR-15 is a bandaid, however probably one that can last a long time. Be aware that eventually you will need to fix it properly.

 

My car is in the middle of this right now too!! I have the same exact problem with my car. The floors rusted from the inside out so underneath its fine. And I have a few pinholes as well. I def would like to see what people do for this.

 

POR-15 says for the pinholes put masking tape on the underside and then paint it. They also have a fiberglass mesh you can lay down in the paint and a POR putty that you can fill the holes with.

 

Ordered it today. Hopefully late next week I will have some "after" photos to share.

Thanks for the input.

 

I had a few little rust holes in my trunk , I used a product I found at the NAPA paint store called RUST MORT it killed the rust dead as a doornail and then I just mixed up a little fiberglass and repaired and refinished the floor, it was real easy and looks good and will last for ages as long as you get rid of any leaks that might be contributing to the problem.

 

I used Por-15 and fiberglass on my floor for the same pin hole repair.
It worked awesome. The floor was a little soft and flexed slightly around the area of the holes.
The fiberglass with the Por-15 has made it as solid as new, if not more so.
Follow the directions exactly, as the prep makes all of the difference in your results.
I used their Marine Clean and Metal Prep also.
I pulled out the floor plugs and placed plastic containers under the holes to catch the rinse water from the cleaning and prep process.

Before, but after the initial degreasing/cleaning:

I have used the POR15 and fiberglass mat to repair a number of floor, trunk, and even large rust holes in inner fender wells......works great!!

The main thing to remember is to follow ALL of the instructions very carefully, especially the Marine Clean and Metal Prep, as stated above!

POR15 is practically bulletproof, when applied correctly......BUT......when working with it, be sure to wear old clothes, that you can throw away afterwards....

AND, do NOT get it on anything you don't want to permanently cover......including your skin.......wear latex gloves, and remove any unintentional spillage immediately with POR solvent or laquer thinner, or you will be wearing it for WEEKS!!!

It is always a good idea to be sure you will not have to pee for the duration of the project..........., as it's impossible to remove after cured....and solvent can be painful on certain delicate parts of the body. lol!

 

It just a few tiny pinholes, POR15 will work. I had that issue too. Some surface rust too.
I hung a bright light from the roof, turned out the garage light, got under the car and looked for constellations. For each hole I put a piece of masking tape, then painted the whole floor (after a good clean done the day before.) All went well. Just keep it out of the seatbelt bolt threads.

 

I used those little foam ear plugs in every threaded hole in the floor. You don't want Por-15 in them.
