    What type of glue or 2-part epoxy would you use on this? The rest of the dash is in great shape, just has one this broken piece: [​IMG]

    I haven't found any kind of glue or epoxy that seems to hold on plastics like that. If somebody knows of a product that works, I'd like to hear too.

    I just used small screws going throu parts and a large tie rap cut to length, with a hot glue gun over that witch I am sure doesn't hold much still together after about 6 years, don't won't to touch it

    For that I would be inclined to bend a piece of sheet metal as a hidden support. I looked at mine which is off the car and I believe you could use some small sheet metal screws on the ends to attach it to the surrounding plastic. Scuff both parts with 180 grit to give the epoxy something to bite into (metal and plastic) and use a good metal bearing epoxy (like this JB Weld) and that's as good as you'll get.

    Thanks for the feedback. I was also thinking about using something for a hidden support. I am in no hurry, trying to gather advice for now and will post details when I finally attack it - which will be one of my winter projects!

    Superglue and baking soda. You can build it up as thick as you want once each layer is dry which takes less than 30 sec. Once built up it can be sanded or filed. Add the super glue first then sprinkle baking soda on top, then using a small paint brush, remove excess soda back on the work table to reuse. Then I use an old charge card to slide it back into my container like cocaine.

    To repair the rear plastic flap on the rear of my push lawn mower, I used a piece of 1 mm plastic packing box (or you could use an old charge card or Hotel pass car) then trimmed it to fit, then applied superglue, then backing soda. I built it up to where I wanted it, then smeared black RTV over it.

    The top left and right is a tube with a slot that holds the short rod on each side of the mower. So I used a strong piece of drinking water fridge tubing then made the slot piece which was broke off. The top right had a large square missing which I completely remade.

    Other small cracks had super glue added then a dash of baking soda was applied on top.

    This stuff hardens like a rock. I also use this procedure to fix my Dollar store reading glasses that I use in the garage that seem to crack easily.

    panel adhesive! The stuff they use for repairing composite and plastic bumpers, that stuff sticks like shit to a bed sheet! Smear a bit along a piece of fabric and use that as a backing strip to get stuff in position: butter it on as smooth as possible. Let that dry at least overnight then scuff it down and repeat until you have 3 layers in there. It be like steel.

    Thanks! I might investigate that! I am taking my time in working on it as it will be a while until I am ready to use it. I will be re-enforcing it with a metal strip on the bottom of it either way. Will update as I work on it.

    Just working on cracks on my dash also.
    A local body shop guy fixed me up with a professional repair glue that worked fantastic.
    I think the product name was Fusor.

    Perfect! I have made a metal support reinforcement brace, but no bonding yet. A quick google search showed: and then a search for Fusor on Amazon looks like they have what you are talking about. Might have to look into this and try it out - Thanks!
