   I repaired the cracks in the dash of my 1855 today. I used a soldering pencil and melted the plastic on the back side of the dash. Used the point of the pencil to melt the plastic in the cracks and then used a circular motion to blend the plastic over the crack. I had another junk dash and cut strips of plastic from it to use as "filler rod" in the repaired areas. I built up the area over the cracks by melting the filler rod into the parent plastic, seemed to work pretty well.

   Now, I want to coat the underside of the dash with some sort of epoxy/resin/fiberglass to reinforce the repaired areas. Anyone know of a product that will adhere to the plastic and make a strong repair?

Thanks, Tim

​I've never tried the welding plastic method but have used a lot of bondo over the years. I like the Bondo brand fiberglass resin using the fiberglass mesh. Make sure you clean the areas to be repaired good.

Not sure what's best to try, but whatever you use, do rough up the plastic where it is to be applied to give it something to "hook" to.

You might look up Marine Tex. I used it on my boat and is super strong. It's also waterproof. It also comes in a dark gray, almost black. Not the cheapest but you could probably rebuild the dash from scratch with it.

That stuff will also seal the side of a busted engine block at the coolant level!  Didn't know if it was still around.  Used it many many years ago.

I use this on plastics, Cracked Dash's, Bath Tubs, Fridge racks. Excellent results!

That stuff or JB Plastic Weld or Loctite Plastic Weld are all going to be your best options.  I do a lot of work with 6 wheel amphibious ATV's and their bodies are made of plastic and from what I've found when repairing ABS plastic (what the Massey dash is made of), these epoxies work the best.
