In2Carz Posted April 2 Share Posted April 2 I have an original dealer promo model for the 1969 Ford Mustang. This is an extremely rare and valuable collectible. Unfortunately, one of the windshield pillars has been damaged (see pictures). I have four questions. Can this be repaired in such a way as to be unnoticeable when completed? If it were your item, would you attempt to make the repair or leave it as is? What would be the best way to repair this type of damage? Presuming this repair is sufficiently difficult as to not be recommended for an amateur, where would recommend sending it to be repaired? Thank you in advance for your assistance in this matter!

iamsuperdan Posted April 2 Share Posted April 2 Good thing you still have the broken piece. If it was mine, and I wanted to keep it in original condition, I would glue the piece back in place, using the bare minimum of glue. The cracks would always be visible, but most probably wouldn't notice. 1 Quote Link to comment Share on other sites More sharing options...
Mark Posted April 2 Share Posted April 2 I'd put the pieces back, but unless the rest of the body is really trashed I wouldn't even think about repainting or anything remotely like it. Quote Link to comment Share on other sites More sharing options...
Ace-Garageguy Posted April 2 Share Posted April 2 You need to practice your glue application technique prior to doing it, if it's not something you have already developed skill at. I see most amateur "repairs" doing more harm than good usually. Another thing...that generation of promo is probably ABS, which is a toughened version of kit-style polystyrene. A solvent-type adhesive specifically made for ABS would be recommended, and again, you'll need to practice your application technique, as too much will inevitably spoil the "glass", or the surrounding material. The typical "repair" I see on things like this ends up with poorly controlled blobs of tube-gloo or CA ("supergloo") making the damage look worse than if nothing had been done at all. A well-done repair can be almost undetectable. 2 Quote Link to comment Share on other sites More sharing options...

Any collector would notice a total repair and it’s value would be lost. 1 Quote Link to comment Share on other sites More sharing options...
Mark Posted April 2 Share Posted April 2 I'd also consider bagging the pieces and tucking them into the interior until you have the confidence to dive into this repair. Get experience on less valuable items first. Like Ed Roth used to say: "don't mutilate, unless it's cheap!" 1 Quote Link to comment Share on other sites More sharing options...
bobss396 Posted April 3 Share Posted April 3 You could back the broken pieces up with some thin (.010") styrene strip and let it overlap on the inside so it will be mostly concealed when put back. If you could find a junk body of the same color, make a replacement piece out of that. Quote Link to comment Share on other sites More sharing options...
In2Carz Posted April 4 Author Share Posted April 4 Thank you gentlemen. I will leave it as is for now, and practice on a few cheap models until I fee confident to try the repair. Quote Link to comment Share on other sites More sharing options...
gotnitro? Posted April 4 Share Posted April 4 I'd repair the broken pillar w a UV glue pen. Tiny amount of glue, cure in seconds w UV light and done . Amazon sells them for around 5 dollars. I'm using one to repair 3d printed parts that normal " super glues" have difficulty bonding to, works excellent Quote Link to comment Share on other sites More sharing options...

How does a UV-curing product cure inside a joint where UV can't reach it to initiate the reaction? Edited April 4 by Ace-Garageguy 1 Quote Link to comment Share on other sites More sharing options...

Apply the glue to the pillar, hold in place. Flip pen over where the light is..press a button to illuminate light holding it near the break...and it hardens the material. JB weld sells one also Quote Link to comment Share on other sites More sharing options...

Warren D Posted April 4 Share Posted April 4 If it were me, I'd use white glue (Elmers) sparingly. It is water soluble so in the future the repair could be re-done without damage to any of the parts. Any overage can be removed with water. 2 Quote Link to comment Share on other sites More sharing options...

A removable repair that leaves no trace is vastly preferable to a half-..... permanent repair. EDIT: One thing I can tell you...an absolutely undetectable repair CAN indeed be accomplished by someone with the requisite skills, including but not limited to color-matching paint for the pillar, and very fine airbrush work. But the cost of such a repair at $35/hr, the absolute minimum anyone having said skills should work for, could very likely run to hundreds of dollars. Considering I've seen an auction estimate of $3000, and a report of one actually selling for $1800 and change, that seems reasonable, but a bodged repair will significantly reduce the potential value.

Pierre Rivard Posted April 6 Share Posted April 6 Canopy glue. Wipe off anything oozing out with a wet Q-tip and this way you can glue it to the glass without damaging it. Quote Link to comment Share on other sites More sharing options...

They're both PVA (polyvinyl acetate), are water soluble when wet, go on white, dry clear, and will peel off with no damage later. Quote Link to comment Share on other sites More sharing options...

It's just that I've had much better results with Canopy glue... Maybe It's just in my mind. OK, gotta go, shrink appointment...😃 Quote Link to comment Share on other sites More sharing options...
