Neil,

I had pretty good luck a couple of years ago just straightening mine out.  Had to repair a few cracks too, but I just took a spray bottle and water and got the back sides good and damp in the warped areas, then put them (vinyl side down) on the concrete with a piece of plywood on them and about 30-40 lbs of weight on the ply until they were dry.  Took a couple of treatments on one really bad one, but they flattened right out.

Of note, however, is that it was about 112F when I was doing it, in low humidity, so in a humid clime, I'm not sure how long it would take for them to dry properly.

 Subject: '90 Wall renovations
 
 I've trying to determine the best method of renovating my
 wall/door
 coverings.� They're in decent shape but fiber boards
 are misshapen from
 water exposure.� The options I've considered are:
 
 1� Replace with 1/8" Bamboo ply
 Two tones are available but am not sure either will look
 good with my
 burgundy metal trim and gray (presently) cabinets.
 Has a tendency to split along the bamboo seams if bent along
 the same.
 Klick rivets/machine bolts will hold the panel more securely
 (more
 locations) than the plastic factory crap.
 
 2� Remove plastic coverings from factory fiber boards
 and replace the fb
 with 1/8" ply after painting exposed surfaces.
 Plastic door skins appear to be welded onto the fiber boards
 so I'm not
 sure if they can be removed without destroying them.
 
 3� Replace the entire wall coverings with sandwich of
 1/8" ply, 1/8" foam
 and gray tweed.
 More money, time and trouble but will look new vs. 25yo.
 I've worked with both before so am comfortable.
 A plain tweed on all panels will look a little homespun
 compared to the
 factory styling.
 Will have to deal with the extra 1/8" by speaker cutouts,
 and such around
 the door handles, latches and window switches.
 Klick rivets/machine bolts will hold the panel more securely
 (more
 locations) than the plastic factory crap.
 May be able to do the lower portions of doors with something
 similar to the
 vinyl material on the B (?) pillars so it appears to be
 more
 factory/stylish.
 
 What would you do?� Please/thanks!
