Auto body repair & detailing: bondo thining, pinholes, body filler

Question
How do I thin out bondo to do a pin hole?  Can I mix it with a small amount of reducer?  This is a two part bondo, for a 72 chevy.  

I have taken down all the paint, to find bondo on some small parts of the door and front fender.  I took it down a bit to far, and would like to coat with a thinned out coat.

Hi Angela,

You can use polyester resin to thin out "bondo". Or better yet you can use a glaze putty to fill the pinholes. Glaze putty is a product that already is pre-thinned for filling pinholes. I like a product called Dolphin Glaze. I think it works great for filling pinholes and small paint nicks. Here's a link where you check it out for yourself: http://www.repaintsupply.com/pd_dolphin.cfm
