Sorry to that see that Bargy but I shouldnt say it no I need to say it grrrrr im going to say it. Preparation is the key, start as you mean to go on. Short cuts will always turn into disaster. And they J mans tip for the day!!!!!!! A tack cloth is your friend for taking out bits in your clear coat whilst its curing each coat. Another tip if your really having dust issues is spray under the body, hence face your surface at the floor and spray up.
Tell you what though man I am loving the concept of this build, pure genius
