Hello, I also am restoring a 1972 31' I have been researching the covering of the bulkheads and cabinets. There are many veneer suppliers , with many thicknesses to choose. Recently i came across a vendor who supplies a veneer with a pre glued backing. If you are going to pay good money for this product you need to ask questions to the supplier. (which i have not done yet).
Since the Airstream gets extremely hot inside when not in use, the right adhesive needs to be researched. The process for re-skinning the existing walls (which appears to be a thin takeoff of wood grain Formica. is to remove the panel in question . The bulkheads have trim or corner moldings which need to be removed ,so the new covering will go under the trim, and look factory done. Depending on the thickness of the veneer, the edge of the panel being covered may need to be sanded to allow for the increased thickness of the panel ( to allow the metal trim to slide on ,for reinstallation.
Since i just found this supplier , you will have to wait , as the name is stored in another computer which is at my winter residence. Should have it in a few days.
I have been rennovating this unit very slowly, as it is a big job. I have 200 hrs on polishing and now am ready for the Cyclo polisher to finish the exterior.
The biggest thing that keeps me going is the brilliance of the shine. I am doing the exterior polish first as it requires the least cash outlay. Then if i loose interest , i can sellout and add $3,500 for the polish job plus extra profit for the fact that it looks cool!
Men have a thing about shine. $$$$$$$$$
Have fun , but be patient!
