Pre-Spraymax sanding question?

[ride92]

So tomorrow is the day that i will be spraying the spraymax on Project Sonar!!! I'm just wondering how much I should be sanding before hand. I'm using 1500 wet and Radare's post says to lightly sand before the final spraymax clear goes on. Should I be sanding until I achieve a uniform smooth dull looking surface on everything or is it alright to leave a little bit of high/low spots where some look a bit shiny-er sort of. I don't mean different area's on the piece lit one big area is dull and the other is shiny, I'm just talking the very little bit of orange peel that is there after doing the duplicolor clear. every part was color sanded before doing the acrylic clear so the paint under the clear is flat and smooth. I just want to make sure I do this right. But damn it sure is alot, and I mean ALOT of sanding if everything has to be uniform. Let me know what you guys think. Thanks
