Would like to mold some fiberglass parts onto steel body (side skirts) I will rivet these on there and which body filler would be best for this procedure? I was thinking fiberglass based?

you need a cross bonding adhesive that can adhere to both the materials in question. Sort of like a panel adhesive for differing substrates. Since both materials have differing expansion rates you will need to use all flexible materials. Filler will have to be a flexible poly glaze, flex additive to primer or flexible 2k, and most paints nowadays are flexible enough on their own. No need for flex agent in base cause it's too thin, but there's a lot of geeks out there who will add the flex additive to primer, base, and clear, but in my opinion most clears have a tad of flex already and base/sealer doesn't need it. So basically using it for primer and a flexible filler is good enough. I would use the cross bonder (Lords) under the mating surfaces around the rivets and flexible filler to smooth out the transition.

He stated he wanted to mold them on, just askin a simple ???
Sorry buttwipe.I mistook your serious question as humor,(I should have known better) I just thought it was funny because a few years back I made the same mistake putting skirts on a 60 buick and couldn't get the tires off until I unscrewed them and it was a major PITA....Speaking of which, after your done smelling your own farts you can also use your own as*hole to go F##K yourself...

Mitmark,Sorry bout that... one thing you dont want to do is glass the rocker skirts to the car ,they'll break off if they come in contact with anything. You can make a mold out of styrofoam and shape it with a cheese grater.Before you lay down any glass give it a heavy coat of wax so the glass dont stick to the mold or the carwhen they're done you would glue them on.but fiberglass cracks or breaks so it isnt the best material to use down on the rockers ,are there any urathane (plastic) ground effects available ???

Just the fiberglass :( I'm aware of it cracking easily if I hit anything with it but this would be a car that I'd drive on nice days.
I know a guy who molded a fiberglass hood scoop on his metal hood with body filler and it held up pretty good. It was on his drag race car (68 Charger with Hemi hood scoop)
