I have been doing some research on this topic of repairing my plastic dash box. I have seen a number of methods used. The one I like the best is the one MH81 used but he said the product he used was no longer available. I found this during my research & with shipping these folks have the best deal. You can also search this on YouTube to see several ways this product has been used from repairing simple cracks to actually prefab missing pieces. This product sounds like the same stuff MH81 described but under another name. I will be using it & I will post some pics on how it worked out.
Here is the link that sold me on this product.
