Apparently there’s been a number of changes over the years regarding what whatI’m looking for is called. Last time I bought it was from Menards and it was called 1/8" MDF. In the past I bought similar stuff and it was called tempered hardboard. Now home Depot calls what I’ve always called masonite tempered hardboard.
What I’m looking for is smooth on both sides. Color doesn’t matter but it’s always been honey colored, not dark brown. I haven’t tried Star but the the blue, orange, and green stores don’t have what I’m looking for. Does anybody have a local source?
