Subject : Veneer over flat aluminum?
Posted : 2006-05-10 8:35 PM

I want to glue bubinga waterfall veneer to a flat piece of aluminum that will become the dashboard for a 1965 Cobra. I would also like to know a good top coat for this veneer. My desire is to have a semi-gloss look when complete. The aluminum is approximately 50 inches long and 9 inches wide. Any ideas would be greatly appreciated.

Personally for interior car use I would go with a catalyzed polyurethane automotive finish. These finishes are usually high gloss so you could add some flattening agent to dull it down a bit.

Darryl, thanks for the input regarding the top coat. Also, please recommend a product or method to glue the veneer to the aluminum panel. Again, thanks for the feedback. Bill

Bill,

For aluminum you definitely want to use polyurethane glue. Remember to use a very light coat as it will foam up during the curing process. I would also give the aluminum a good coarse sanding before gluing.

Hey Darryl...

Would you mind discussing why polyurethane glue?

Before your response, I was thinking West System would be the choice. I thought that epoxy would be best to avoid the foaming and expansion of poly's.

Could you expand a little more? I'm not sure why poly is best here.

Thanks.

Brian,

Although epoxy would do the job just as well I generally stay away from it for veneering because its such a high saturator and cleaning up all the bleed through is a major pain. I find epoxy very difficult to scrape and sand.

The more I use polyurethane the more I like it for these odd gluing applications. Surfaces that no other glue will stick to polyurethane usually does a great job. Once you get the feel of how much to use its not that hard to keep the foaming to a minimum. What does bleed through is not that hard to remove and sands fairly easily. I would never make it my main veneering glue but for these non-porous, non-wood surfaces I've had great success with it.

Sincerely
Darryl Keil

I will further endorse Darryl's recommendation for poly glue. I too have great success with it despite it's drawbacks of foaming, set-time, and being somewhat nasty to wipe off things it drips onto. If you vacuum press with it the foaming isn't an issue. Be sure to isolate this glue from your polyurethane vacuum bag.
