My 4X6 is so old,,,,,,,,,,, (HOW OLD IS IT!!!!),,, that my saw was manufactured in the USA!!
It is perfect, but, almost never used,, because I have a 9X16 saw, also.
Actually, I carried the 9X16 outside last week, and sprayed it with Walmart Engine Degreaser, then hosed it off.
I bought the 9X16 used in 2001, and that was the last time it had a "bath".
The saw is SO big, that I emptied two cans of WD 40 on it after the water had dried, to protect the areas with no paint.
I bought the 4X6 used, about 1990.
