fiberglass to metal or epoxy??

I am customizing my stock metal running boards on my 50 chevy truck. I installed wider fenders and need to flare them at the rear to meet the wider fender. I will do the mods with metal but want to smooth out the grooves in the top of the board with fiberglas mat or cloth. after I blast them should I go ahead and epoxy prime them or would the glass get a better bond to bare metal? epoxy wold give corosion protection.

Polyester resin will stick well enough to metal for cosmetic purposes if done properly. Surfaces should be very coarsely sanded and very clean. I have heard that it sticks better to epoxy primer but have never tried it myself and would advise you contact the manufacturers of the primer before trying it.

If in doubt or if the work will be taking strain of people stepping on the running boards you could use epoxy resin for your fiberglass work in which case you do not need a primer. (If you use epoxy resin you cannot use regular fiberglass mat.)

i have used kitty hair (a fiberglass reinforced filler) straight on to metal. The car sat outside at plus 100 and down to minus 25, kit a wall at 60mph and the filler did not loosen or degrade in any way. I was taught straight to metal but I have also seen a sealer/primer used first.

thanks, I actually talked to Barry from SPI today and he recomended the same thing, but on top of the epoxy primer. so I will make the mods with the metal and do the finishing work with kitty hair
