Have a 40yrs old homemade metregon speaker, some of the wood venners on top and curved front start to peeling/bubble up(maybe caused by water )also the front curved panel where the verneers matched also started to peel.

Any LAZY way to re-glue them back and really not going to remove the old veneer and put a new veneer on? I know the new veneer will look good but it's a big job for me,(take ot the old/sanded/stain the new veneer and match the 40yrs old wood colour).

Thanks again
