Hi, I had my Vintage Radio refurbished and customized here : https://www.vintagecarradio.com/vintage-radio. You may ask for their advice if you any concerns about your car.

Just saw this. Very cool!
I do, however, question the use of white glue. I suppose that it really doesn't matter, except that everything I've ever seen associated with speaker construction used solvent based adhesives, as opposed to water based. Just gave me a WTH moment.
But if it works...

I just refoamed 4 8" woofers, they gave me white water based glue, I'd say it works well since if you get any on yourself you can just wash it off.
On a car it *could* be a problem, but for home if they get wet you have bigger problems than your speakers.
BTW, this is not Elmers, although it looks like it, that stuff is too brittle, the stuff I used is more flexible.

I would say however not to use too much, I only needed half of what they gave me, it is one of those Goldiloks things, use enough to do the job, but not too much
also I do not think cutting out the dust cover and shimming is necessary if the covers are in good shape, if not yeah, but your mileage may vary.
This is easy, the main thing is to get off the remaining foam and adhesive, I used a toothbrush to scrub it off the cone.
here is a pic of the completed job

I saved $125 by doing it myself, and I did as good if not better than the "pro" I paid to do it before who did a kind of messy job

To be sure the voice coil never scrapes you should remove the dust cap and shim the VC. Then glue the surround. When it’s all dry I then water down a bit of glue and yes it to “paint” the entire surround. It provides a bit of dampening and seals the gap at the surround gasket. It will smooth out the sound of the sub.
