    Lots of filler, support (eg balsa wood), glass reinforced filler, sanding and patience!

    Make sure you prep the area yout are sticking the filler to by degreasing it and roughing it up with paper to give the bondo a 'key' and use penty of support structure to stop it bending.

    we have a product called isopon over here, it comes in 2 forms like your bondo. the brittle but easily worked plain stuff and the glass reinforced stuff what is more like araldite. the former (like what you have got) is very prone to cracking when used in thick sections and when the substrate (what it is bonded to) flexes. Fillers like bondo are only designed to be used as thin layers to pad out dents etc so i guess when you are trying to fill a gap between the screen and the dash it is having to take load due to flexing and it only has a small contact area with the dash so it really is not suitable. Try and get something more like an epoxy with fibres in and don't rely on it being able to take load/flexing etc.

    Bondo is not a structual material. It won't take any load and you may as well use cake icing!

    Like Scouse Monkey said use epoxy or get the reinforced bondo. It is much stronger then just regular bondo. Use the reinforced stuff to fill in the big hole and then sand it down. Then use the bondo you have to fill in the holes to get it smooth.

    This is the one i'm talking about.

    You have to have a very strong mechanical bond before using the filler. Filler is not an adhesive. PowerPoxy's Poxy Weld is Kevlar reinforced. Use that to glue the parts together first, but you still need to insure that the areas to be bonded are clean an well scuffed with 80-180 grit scratches.

    3M Automix Plastic Repair is an even better filler to use, but its pricey. That Bondo brand stuff is crap. Go to an Auto Body Supply store and get a glazing filler like Evercoat Metal-Glaze its much easier to use on small projects.

    You can also make a decent sandable filler out of the Poxy Weld by mixing it with Microballoons but you have to work fast.

    Body shop supply places will have the Automix too but its expensive. The Poxy Weld and Evercoat combo is less expensive. You can try calling for a PowerPoxy distributor the number is at www.powerpoxy.com. Not much else is there on the website though!

    You can use the reinforced bondos as an adhesive, but they just don't stick as well as epoxy does. Just remember that polyester filler don't stick well to epoxy either. So I keep the epoxy on the back and the polyester resin based filler filler on the front. If it does go over some epoxy its just a thin seam line.

    I gave up on that Dominion Sure-Seal stuff. I did get one worthless reply, but the replies take 2 weeks to arrive. If it magically appears on my doorstep I'll try it out.

    I used regular bondo and they are starting to crack on the edge, not a good idea.
