joe,
You have just confirmed my point. I always use 120 grit followed by 180 or 240 before applying any paint. On occasion I will use 300 grit, which has always been more than fine enough to produce a glass smooth finish.
I basically told Mrs T that 240 is suitable for her needs (just providing a key) and that there is no need to go so fine as 400 and you both jumped down my throat.
