Thank you! The seat I have on it now ( can’t remember if it’s Yamiya or something else) looks good, but as I recall the pattern and exact shape doesn’t match my original.  My original seat just sits though, and I just brought it inside because the cold/hot temps from being in my shop is making it worse. What do you use to soften? I’ve used Armorall but it doesn’t seem to help. I will look for the red foam. I don’t want to sell it. If I ever need to sell my sandcast, it’ll go with it.
