Ok, so I got it done with 40 grit sandpaper, boy was it a biatch. MMan, there are a few light gouges with the 40 grit, I couldn't go any higher, cause it was difficult enough just to do it with 40 grit, even tried an electric job, but needed to use alot of pressure by hand to get it done.
Anyhow, looks good from 11 feet back, there are some dull area's were the melamine was taken back further than other area's. If it doesn't look good with the PJ, I'll paint it.
I looked at the paint section in town and they have a Dulux Vivid White Flat Acrylic (Wash and Wear), the store person said flat meant matte, on the tin it said 0% reflection. I think this will be the best way to go, it's wash and wear and can be easily cleaned. Now that the melamine has been sanded, it should stick very well. http://www.dulux.com.au/products/dulux-interior-products/walls/product-detail?product=2250
MMan, is there any other tint I should add to the Vivid White Flat?
Do I need to undercoat it?
