Here's an idea I had, borrowing from some other forums. Anyone can post tips here. For example...

Three things I learned about doing bondo work...

1. Don't wait for the filler to completely harden. There's a stage right before that, where it sands like cheese. You'll save TONS of time.

2. Since #1 is a farily small window, work the filler in small areas.

You'll get the feel for both #1 and #2.

3. Get different colored fillers, or get some gel coat tints to mix in the filler. Do each layer with a different color, so you can always tell how far you've sanded.

If this gets going, maybe we can sticky it. Other topics could be particularly difficult cars to install on, etc.
