I have a pair of JBL 4312A's that I bought recently. I committed fairly early on to re-veneering them because there were a few really poor repairs to corners that had obviously been damaged. We're talking colored wood wax covering bondo seeping through damaged and re-glued veneer. These poor repairs hid some softened MDF that needed to be removed.

I have spent a week or so removing the bad material, replacing it with wood epoxy, and getting sharp and solid corners back. They're pretty much ready for veneer now, but I have a few things I need to decide.

I decided to not try to completely remove the old veneer because of advice I read on this site (but in 10+ year old threads). People had said removing old veneer from MDF cabinets is a huge can of worms and basically results in a loss of will to live. I can see this being the case -- even with tens of hours with a heat gun, a good scraper and the patience of a saint, you're left with rough MDF coated in glue. Trying to sand off the glue gums up the paper, and you end up wondering if you should just burn the cabinets. Finally, I am fairly convinced that the original veneer is adhered well.

I am going to be veneering with new paper-backed veneer, probably teak. I don't mind the original American walnut, but it's hard to find new veneer that isn't a lot darker than the original stuff (that probably came from older trees). And I really like teak.

ACTUAL QUESTION(S) BELOW:

So the question is, which method of veneering is most appropriate for veneering over the top of old veneer? I am tempted by the method I've read about here (and elsewhere) involving multiple coats of Titebond II on the veneer and cabinet, letting it dry, then fixing it by re-activating the glue with an iron. A lot of people have had great success with this method, and there are even some decent YT videos showing the method.

The nagging issue is the risk that applying heat to activate the glue may end up softening the old glue holding the original veneer. For this reason some people have recommend contact cement or a 'cold press' method (e.g. same glue but applying veneer while glue is still wet and clamping).

The problem with a cold press method for me is I currently live in an apartment in Spain. It would cost a lot and take a lot of space to buy 4 or more F-clamps large enough to clamp the veneer down properly. And as far as contact cement is concerned, it sounds like a decent idea except that people have mentioned that it may not be great long term since it never truly hardens, and is susceptible to high humidity (I live in a humid city next to the Mediterranean).

So, for those that have veneered over veneer, what method(s) have you used? What worked and what didn't? What would you recommend given the constraints of 1) small apartment, and 2) not wanting to buy a bunch of expensive tools for one time use?

Thanks in advance.
