Spray filler / primer?

[tlr]

Do you guys recommend spray filler / primer that can be sanded to smooth fiberglassed props before applying regular primer and paint?

I used Bondo filler and putty on my Daft Punk helmet but it was a pain to work with and hard to get everything smooth.

Thanks.

If your coating fiberglass there is nothing better than sticking with the same chem. Here's what I use, you need a large needle/nozzle combo for you gun.
