Putty or bondo?
Guys,
I am almost finish with my fiberglass box. Also I am creating a ring for the sub with mdf (raising it).
What should I use to make the surface smooth?
Putty or bondo? Which one is less harmful or messy.

Yeah, but be careful with the bondo'ed surface after you are done because bondo has a tendency to make stress cracks.

Bondo is nice, but it dries really fast so sometimes it is tough to work with. But to make it nicer and to protect it from cracking you can coat the bondo with a thin layer of epoxy (no glass, just the resin).

Tony, how are you mounting the Sub to the riser/top? I am pretty happy with the T-nut & machine screws but I noticed this weekend they had come loose from excessive bass thumping. One screw in fact had almost worked its way undone.
Does anyone have any advice for securing the screw heads and preventing any loosening? I was thinking of lock washers or maybe a different screw type all together. BTWL I used 3/4" MDF top with 3/4" ring wood glued. Dremelled out holes and T-nuts on the back. 2" #8 straight machine screws.

I would like to see pics when you finish the box, I am hoping someone will make custom boxes for our car, as my current box for two 10's somehow barely fits and I had to remove rear hatch plastics for the clearance to work.
I am going to use drywall screws (3/4 inch). I have pretty good luck with them in the past.
Thanks,
Chris

I was going to use drywall to attach the MDF top to the Fiberglass bottom, but I noticed with my last box if you take the sub out as many times as I do, the holes start to get wider and don't grip as tight. My idea with the second box was to use the T-nuts on the underside with straight machine bolts. I am going to try lock-washers on top to keep them from coming loose.

Guys,
Are car bondo and fiberglass bondo the same?
When I bought it at Home Depot, I just look at a picture with a car/boat. But when I took it home it say bondo for fiberglass.
Any difference inhaling any of these bondo .

No, car bondo is not fiberglass. The problem is that the company name that makes the epoxy resin for FG and the car bondo is called "Bondo"
Fiberglass resign is most often called polyester resin, the bondo that you want is called Body Filler. It's made by bondo, so bondo is just a trade name, it's not what the stuff is actually called.
