My friend & I were going to try to fix a dent on his 94 Mustang. I was looking to buy some body filler but I am confused as to which one to get.[/align]Anybody have any opinions on which of these would work best?[/align][/align][/align]http://www.autobodytoolmart.com/c-49...s.aspx?cid=FM1[/align]

 

The 3M lightweight will be fine.
Regular ol' Bondo,available at all auto parts stores is fine also.

Mix either one according to directions and apply to as small a dent as you can.Using a lot of filler to "cover up" a dent will ultimately fail due to cracking.
