What is the difference between regular bondo and fiberglass bondo?
Re: Is there really a difference between regular Bondo and fiberglass reinforced Bond#N#Yes, big difference. Fiberglass-reinforced bondo (whether with short-strand or finer additives) is quite a bit stronger, but it is also A LOT harder to sand.

Regular bondo can still be quite a bit of work to sand down; you can get featherlight types that detail and sand more easily, but they won't really add any structural strength. I Just lay 2-3 layers of fiberglass matt and resin on my pieces, then finish with featherlight on the exterior.

After that, I start bondoing/sanding/priming/repeat on the exterior until it's where I want it. So all the mat is on the inside, just a resin base and bondo on the outside. That's what I do anyways.
