I tried Howard Restore-A-Finish based on advice from an antique furniture dealer. Didn't even know this had come up on the forums. I needed to do something but didn't want to deal with Formby's or something more invasive. I used Howard's in golden oak for the oak interior of my 1960
TW. There was finish damage from water spotting on the wood near the bath vanity. I was amazed. Here is the before and after.
I did the whole trailer last Sunday and today the wood had lightened up a bit but the water damage is still gone. Never used steel wool, just a soft cloth. The odors from the product were minimal compared to other refinishers I've used. Today I followed up with Howard Feed-N-Wax. Now all the wood just glows, I'm totally pleased with this quick fix.
