I have shown this prototype here before, so this topic is dedicated to its repair. It is always controversial to repair prototypes as one inevitably alters the historic value of the model. I have many prototypes, many with defects, hence have to scrutinize these repair decisions one by one. In this case the damages were so many that the market value of the model was already ruined so I decided for repair it that ultimately brought satisfaction for me and now I have a presentable model. I hope you find a value in this post as I utilized magnets, a topic that I don't remember being discussed here. Many DM cars use magnets but the idea truly came from Doug Whyte's YouTube channel, link to the video at the bottom of this post.

Here are the before pictures, you can see the windshield is broken and many parts are missing. What is not visible is that the hinges of the hood lid were broken and the hood was falling every time the model is turned upside-down.

The pictures bellow are self explanatory, but basically I mounted 4 magnets (2x1mm) in order to create 2 magnetic hinges. The result is not a perfect operation, but the hood lid doesn't fall off anymore and with careful manipulation could be opened and poised.

Further repairs included: windshield replacement, repaired spare tire bay, added: spinners, shifter stick, passenger side wiper, rear-bumper, driver side mirror. The most challenging repair was the replacement of the windshield as I did not want to open the model (in order to maximally save its authenticity). The windshield is screwed to the body and the access for the screws requires disassembling the car. So I ended up removing the windshield from above, leaving some remnants of the windshield brackets between the body and the dashboard (sorry I did not take any pictures of this phase, but on the last picture above you can see the gap from the removed windshield). The new windshield was glued from above using UV resin. Pictures of the completed model will be added later.

Wow!  I've frequently used those mini-magnets in a few of my modification builds.  However, I've never used them for assembly!  That's just too clever!

Here is the "finished car", there are few other parts that I need when I disassemble another donor car.

Next project involves "dechroming" DM chromed part, stay tuned...

thats extraordinary Chav, well done. Sorry but I dont quite get how you removed the damaged windshield. I can where it is separated. Did you cleanup and use the original windscreen frame?

thanks

Everything seems to have worked out nicely Chav....but (personally ) I would've been more comfortable taking this model apart to repair that windshield.  What you did took real guts! 😬 😬 

Very cool Vette! 😎

The original windshield was broken and was missing a 1/2 inch piece, I was considering repairing it but gave up. I used a spare windshield from a green 1966 Vette cabriolet (the ones that have diecast rot), I took that car apart and pulled an intact windshield. to remove the broken windshield I chopped whatever pieces I could and then used eXacto knife to cut the brackets remnants between the body and the dash board. That was a difficult operation because you have to apply lots of force but also protect the paint on both sides. Once that cleanup was completed, I cut the corresponding hidden parts of the new windshield until it fit in the gap between the dashboard and the car body. Gluing it in place securely and cleanly with UV resin was another challenge (will elaborate further later).

Any other model, yes, I agree with you. This one however was a development prototype, opening it up inevitably will cause several broken parts and pins (I had just opened the donor car and knew exactly how it was assembled). I considered repairing the windshield as well. By the way the 2 side windows frames were also broken, I ended up repairing those.

See, the bottom has no backstamp, these are very rare, especially for DM, I did not want to touch this part, there are 4 hidden screws.

Well, you got me there.....  knowing exactly what you were in for (by messing around with your donor  ) is justification enough to NOT open her up  and risk FURTHER damage/lower value.  I get it.

@geoff-jowett Just to finish from earlier today ... I was on hurry this morning,

I love to work with UV resin, but it has a major issue that is especially dangerous around the windows' plastics. The resin threads tiny filaments that are probably electrostatically attracted to the plastic, and the issue is more pronounced when the resin is a bit older or stayed on air for several minutes. You don't even see these filaments when they mess up your "glass", you see them later when you inspect your work, extremely annoying. The only way to repair the damage is by polishing the plastic that is not a pleasant process. More to come on this issue, I have to repair a window messed with superglue and will give more details and pictures ... another prototype repair.

thanks Chav, very very keen to see what you can do with the messed with superglue window

I just read this post Chan. What a professional repair. I could ever have attempted this. I really enjoyed your comments and this discussion.
