Can I use foil duct tape to repair holes in car fender?

I have used plain duct tape, a special black pvc kind resistant to sunlight, touch up painted to match. Just depends on how picky you are, me I've got REAL problems to worry about, my car just gets me from point A to point B.

Look into Bondo:

bondo - Google Product Search

A lot of places don't sell that any longer since 9/11

What is it about Bondo they don't like?

If I told you, I'd have to kill you, then eat my laptop. But I hear Iguanatanimo is lovely this time of year.
