front clip repair

I recently got a decent front clip from a local junk yard, it has a split in the lower right half a few inches long (alot better than my original). I was wondering what would be the best thing to use to patch it up. I can work fairly well with bondo, but I've never used it on this polyurethane-like plastic stuff before. Anyone have any recomendations? Good web sites on this? I'd appreciate any help you can offer.

Thanks in advance,

Use fiberglass bondo instead of the regular stuff. The rest is still body filler 101.

cool, I can work with that.
Thanks for the help man.

peace,
