Help. I put some fiberglass cloth on the insides of my floorpans to cover some large pinholes and the resin doesn't want to cure. I did it Sunday, and after three days it's still sticky.

The weather was around 60 degrees, so I doubled the amount of hardener. When I saw it didn't harden by Sunday night, I put a space heater in the car and left it on all day Monday. Didn't seem to help.

Only thing I can think of is maybe the material was too old. Any idea on the shelf of this stuff? It was a gallon that I opened and first used over three years ago.

Do you think a fresh batch of resin with extra hardener put on top of what's there would help it to cure? It'd be a real mess cleaning it up, so I'm open to any and all suggestions..

I think you have a mess to clean up. I don't know of any way to get this stuff to cure once it starts doing this. And I've had this same problem a few times myself. I think it does have something to do with the shelf life.

But I have another thought to add. This might be a blessing in disguise. This sort of material is not a very good choice for floorpan repair. I assume you used the fiberglass repair kit commonly found at Wal Mart and most auto supply stores. If so, this stuff will allow moisture to seep in and the metal will start rusting beneath it. Por makes a fibermat material that contains metal strands in its fibers, and you apply it by laying it down and painting Por 15 over the top of it. It'll be water and rustproof when you're done. You can then use Por putty to smooth it out.

There's more info here:

Since you already put the stuff down, try a heat lamp or light bulb or some other way to get some heat on the area for a few hours.
It just might harden it? Just be carefull not to catch the carpet or anything else on fire.

The most common cause for this outside of not adding enough hardener to begin with is an out dated hardener. The shelf life on the stuff is only about six months. I forget how to read the date but it is printed on the end of the tube where it gets melted together.

I have had the same problem once with polyester primer, I will never make that mistake again!

By the way, if you mix up some more resin with new hardener in it and brush it over what you have, it can soak into the soft resin and harden it. Just a thought http://www.chevelles.com/forum/smile.gif

try to scrape as much of it off as possible with a metal knife, then either do like MARTINSR said or remove all of it. use acetone to clean up with. i highly recomend going the por-15 rout. it will last longer then anything else other then replacing the metal floor pan.
