POR-15 and fiberglass question.

    My daily driver has a few rust holes in the floor pans - its a 90 Dodge Daytona which which I'm trying to keep another year or two.

    I put some POR-15 on the bottom to lock the rust, but am unsure how I want to patch the holes, which are about 4 x 6 inches.

    The rug will be removed and the holes patched from inside the car - I was thinking of using fiberglass matt. Should I just POR the matt down, or stick with epoxy resin? If I do the traditional fiberglass/resin repair, can I POR the metal first, or will I need bare metal to bond to?

    Hole in floor is to drop :beer cans through????? (option)????

    If cosmetics don't count how about pop riveting in some sheetmetal and coating it or fiberglassing over it. I have been down this road before. I think fiberglass by itself may not stand up too long.

    I've riveted signs on floors before, and have also used a few layers of fiberglass. The car probably won't last 2 years. Since its a "sports" car, you can't really get your weight on the floor as it is.

    I just figured POR-15 would be easier than mixing the resin - and I'm feeling a bit lazy.

    I'm also using this car to practice with POR-15 for when I get around to fixing up the Buick.

    You can use the POR-15 as resin for fiberglass matt. Will need a few extra layers of glass to keep from being porous. I would not use this in an area looking for structural strength.

    Its not something that needs a lot of structural integrity - I just want it to be firm.

    I did a few experiments, and it looks like a layer of cloth and 3 of matt should give a repair that is quite firm - so long as its not abused.

    My dad's 86 Sentra had a hugeass hole in the passenger side floor a few years ago, and I riveted a piece of heating duct steel (that I un-bent...I didn't have anything else :grin: ) and then put down two layers of matte and resin. I used some hella thick matte, the stuff they use on boats. I think that was about 4 years ago now, and it's still going strong. It's really f-ing strong too. Probably one of the strongest points on that p.o.s. :beer

    So anyhow, my point is that it should be fine to do that on your car, as I doubt that anyone is gonna care how it's put together but you.

    Very true. I'm just being lazy about it, lol. I've done straight fiberglass on a camaro floor and it was very solid. I just don't want to mess with mixing resin or cutting metal.
