    did you use enough hardener and mix it properly?

    how warm is it where you are working? Cold will prevent it going off.

      it's arround 60 here, it was a little cold last night
      but i'm at work now and i've it out side in the sun and still now done, it's getting a little bit hard.....
      so every time i want to do bondo i'll wait this long or it's something wrong i'm doing.....i hope it's something wrong i'm doing.

      what is the best type of bondo i should use.

        No, you shouldn't have to wait this long. Bondo should harden with in 5 to 10 minutes. You may not have mixed in enough hardner. Also I believe it is recommend to use bondo when the temp is above 60 degree, read the instruction on can, it should tell you the temperature. Also it was probably too cold over night for it to harden. Try to use a space heater to make it harden faster.

          yea it should be hard and sandable in 5-10 min like Quattro-A4 said. i always over add hardener. and make it dark pink.

          i would scrape it off and redo it, since it should be hard in minutes.

              if never did it, then you should be careful, I will try to give you as many pointers as i can remember right now, and maybe some people can add:
              1. The Bondo and Hardner mix should match the color of the mixing spatula thing they give you.
              2. Try not to put bondo all over the console and teh frame, just in the cracks and space between the two.
              3. if you have to sand a lot and at slower pace, do it, perfection will make you smile everytime you get into your car.
              4. Take time to put on the primer. Two coats 6" away every 10-15 minutes (5 times...thats right 5 times) it makes a difference. Make sure ot sand lightly after 10-15 minutes of waiting.
              5. Look at number 4 but do it with the paint color. Vynil or however you spell it, paint looks good. 6-7 coats. Do not make the mistake of spraying close and making such thick layers that they reflect...then it sucks. Following this info and you shall succeed.

              as far is what to use: Putty Bondo is fine for cosmetics and some structure, but for structure you have choices:
              1. Superglue...my choice...its perfect (lots of it)
              2. fiberglass (find tutorials yourself...there are plenty)
              3. improwise... heat-melt the plastic...whatever you feel safe with.
              If I said somehting that is incorrect, someone please correct me.
              Also visit this thread of mine...it has pictures of my console being done (here you can see the bondo color, the proceeder, and more. ) http://www.mp3car.com/vbulletin/showthread.php?t=39817

              good luck

                  make an MDF frame or summit and bond it it with epoxy. Use Bondo only for thin surface finishing. The fibreglass reinforced stuff is better for structural work.Alluminium mesh and stuff may also work - basically the stuff you find down your car parts place for fxing bodywork.

                          Glazing and spot putty will shrink like crazy and takes forever to dry with an application like that. I only use it for filling the very few pinholes that get past my filler and primer steps. When you spray over it with primer, it softens and shrinks back into the sandscratches below. I'd sand it off and get that surface perfect with just bondo.

                            Spot putty is for filling in pin holes and rock chips etc. It is not strong enough for what you are doing.

                            I buy bondo by the gallon and I get the Rage Gold brand because it is a good brand.

                            For every cup of bondo add a teaspoon of hardener. Mix mix mix mix so it is all one color. Bondo chemically dries and it will be hard enough to re-shape in about 3 minutes then hard enough to finish sand in about 10. Still let it dry for about 1 hour before applying primer. Apply a nice two part epoxy primer to really seal the panel and sand it smooth with 600 grit wet or dry sand paper using a water bottle to keep it wet as you sand. This provides the very best and smoothest surface.

                            Most of you guys are using spray cans so getting a two part epoxy primer is probably not going to work for you. What I would suggest is when you get the surface PERFECT and ready for primer, take it down to a body shop and have them prime and paint it for you. They'll probably charge you $50.00 to do a nice job. Most shops have a lot of left over paint so if you tell them you just want a basic silver or black or something and are not particular about an exact color, then they will not have to charge you extra for the paint.
