The issue with JB is that it's going to take a lot of work to smooth out all the welds so they can't be seen and then on top of that the whole model may need to be refinished. While this may preserve some nostalgic value, the car is no longer "original." I'm not sure if that matters to Brad, nor if he has the time and effort to dedicate to what could be a really difficult miniature reconstruction.

I've thankfully been able to find brand new, in box originals of a few die-cast cars of my youth. The copies I had weren't smashed to pieces but definitely showed a lot of damage/wear and I really appreciate having both the clean and used copies.

I'm not familiar with the WRX model, but there are a number of forums that specialize in this type of thing. Unfortunately I've been finding lately that Google's performance on some forums isn't very complete, which I've verified by using the "site:" prefix. This may need you to join a couple of other forums to perform some searches and/or post a few requests. Something I've also just done in a scale model forum.

Oh.. And welcome back Brad! Definitely don't try the JB weld on the empeg, in case Mark wasn't talking about the car.
