Ok guys looking for a little sound advice.

Q1

I Have decided to spray the wing of my cossie myself. I got my old compressor out and got a new spray gun for the job. So far i have sprayed the wing in 2pak primer, the paint is hard and dry, but it has reacted a little in some places. Im thinking of using a little filler to fill these gaps in.... Is this a good idea or should i strip the wing again?

Q2

Once the wing is primered to an accecptial condition i will be painting the wing in flint grey. I dont have an issue with spraying the metalic, but what concerns me is the laquer. I have never sprayed laquer before and i was wondering how long should i wait before i spray? also i have been told that you can use 2000 grade paper with pleanty of fairy liquid to temove the orange peal effect.

What do you think........
