For the life of me, I can't find anything using the search.. I know it's been discussed before.

Is there such a thing as SMC resin? I need to help with some repairs on a friend's rear clip (and some modifications to mine later on down the road) but I don't know if we can use regular resin or if the SMC is the way to go here.

Thanks in advance.

SMC stands for Sheet Molding Compound, you can't get the resin part of it separately. For repairs you need to get a product that's compatible with SMC, and body shop supply will be able to fix you up.

Try http://www.autobodytoolmart.com for starters, they've got an 800 number you can call and they're easy to deal with.

I've been using this with no problems. Most paint supply stores have it on the shelf.

Fiberglass resin and mat worked great on my decklids...but dont use it on the flexible panels like bumpers, fenders and rockers.

I use Bondo brand fiberglass repair resin with the fibers in the mix. It works well and sands out good. After using the fiberglass to fill the repair, I use a skim coat of regular Bondo to feather out the edges because the fiberglass doesn't feather out well.

If you are repairing the flexible panels on the car, use the NAPA 2 part repair material they sell for just this kind of damage.

Thanks for the input, +'s all around.

If you just want a resin, it should say on the label 'SMC compatible'. I know that Marson makes it and I'm sure others do as well. Most parts stores that carry some body work supplies should have it or at least be able to order it.

Or you can order it thru catalog sales at http://www.ecklers.com

More good info, thanks! You two already had plusses from me.

So what is it that makes it SMC compatible? I assume a non-SMC compatible product could be prone to de-lamination from the original SMC panel and cracking around the repair?

Carquest and NAPA carries it in Ontario.

Probably has to do with the fact that SMC has a release agent built into it.

The SMC panels (hood, roof, rear deck) Flex more than fiberglas. You could get by with fiberglas resin if you get a large consistent contact area, but cracks will most likely develop because of vibration, temp variation, uneven expansion rates. The SMC compound I've used works flawlessly. Price is about the same, so is strength, the hardener is thicker and more like a paste than f'glas hardener
