Something worth adding to your tool boxes.

I had 6 holes maybe 5/16" diameter under the rear seat area where previous exhaust systems had been bolted up. Not sure why so many but what the hey. For the past 10+ years I had bolts in them just to plug the holes and had planned to have them welded over at some point.

Long story, short, the guy that welded my SFC's in suggested using POR 15 expoxy putty to fill them vs. welding. I bought some, tried it, and it worked pretty darn well. Very easy to use and form/shape if you keep your hands and putty knife wet. After minor sanding and painting I think it looks as good as a welds over the holes would have.

It comes as two bars maybe 8" long, A and B that you cut pieces off of and knead together. I used maybe 1" off each bar so I have a bunch left for other uses. Cost was just under $25.00.

I used POR putty on my floor pan and trunk holes as well, it worked great, some of the holes I also used their angle hair fiberglass to reinforce it, its like steel now. great product.

por power mesh, which is woven fiberglass mat, soaked in por-15 gets as hard as steel also. i did a place in the floor of a 71 nova and after it hardened i hit it with a hammer to see if i could break it, hurt my hand instead.

For small holes POR also makes some stuff that comes in a tube like toothpaste. I applied tape to the bottom of the hole and put some in and let it cure up. This was on a core support that had hood pin holes in it. It filled them up with two applications. Worked great and was very solid, easy scuff paint and match. My core support was in dire straits anyway so I tried the stuff on it. I will use it again for other little stuff but have not gotten the change to do any of those things yet as the car is still in paint prison.

I've used this with great results too, before I bought my mig.

So, kinda like JB Weld I guess??

I used a piece of masking tape on one side and backfilled with seam sealer on some of my holes. That was just on ones that were being covered by something else though. Had a whole dang tube of it so had to do something with it after shoring up my trunk pan.....

Hmmmm......rocker panel in a tube?

Pretty similar. I think the POR 15 is easier to use but I last used JB Weld around 20 years ago so I could be wrong.

It's different from JB Weld. JB Weld is more difficult. I've used both the POR putty and the mesh. Both work amazingly well. Over a 20 year period I am not sure which one, the JB or the POR, will hold up the best.
