A couple of months ago I was watching My Classic Car and saw a product that was a body filler, I believe. Anyways, it mixed with a hardner and dried to almost a metal state. After they applied it, they then shaved it down or whatever to form the shape they needed. They actually used it to fix the rusted area around the window seal. Does anybody know the name of this product?

 

What color was it?

 

There is a fiberglass filler that has fine strands in it. It is as good as metal and will flex without cracking. I think around here they call it resin with tiger hair. It is harder to sand than bondo, but will last. I don't know the manufactuer, but a body/paint supply will have it. It comes in a plastic bag with the hardner seperate.

These guys sell one called Dyna-Hair http://www.autobodystore.com/FillerMatls.shtml

 

I've used the fiberglass filler with FG strands that 67coupe brought up. It was nice stuff and if you use it remember to start shaving it down before it dries completely as its hard as rock. Forget the product name we used but its available at most places you buy automotive supplies.

I got a POR-15 catalog last month with an order and they have a couple of sweet products.. more than I've seen on their websites. Combining their PowerMesh and POR Epoxy Putty would fix such an area. Another product they have is called POR Patch which would be great for this area also.

 

there is a few types of this, most similar in quality and usage
but the brand marglass was just bought out by bondo and now available anyplace bondo is sold as Bondo-Glass

 

Bondo manufactures a short and long strand fiberglass resin. It uses the same hardener as the pink junk, but as stated earlier, is much harder and has some flex. It's great to use if you have to do any shaping.

 

You don't use Bondo. You go to an auto body supply store, where they sell auto paints and supplies and pay for high quality body fillers and glazes. You can also do a search on the web and find suppliers who carry high end filler products. There's a reason why you find Bondo in Pep Boys. And the reason "ain't good".

 

I've had as much success with the bondo line as with kitty hair, but to each his own I suppose

 

there is a product that is called all metal ( I think that is the name) that is similar to bondo but it if full of aluminum so when you apply it it will have a metal sheen to it when sanded down.

 

more than likely it was an alum based filler like this from evercoat http://www.evercoat.com/productDetail.aspx?pID=37

but if your rusted out around the window seals i suggest get it done right the 1st time with new metal and a welder
