As some may remember, my car needs a respray (badly !).


All panels have been damaged so it needs a complete job. I have managed to get hopefully all the stuff I need to do it, 2 compressors, air-fed mask, several spray guns, a mass of different tins of paint, hardener, thinners, primers etc, and it looks like the weather will be good up here for the next 3 days, so I am planning to do it.
I have very limited spray experience so have been reading up what I can but there are still a few nagging queries.
Like :
Obviously I should sand the whole car to key the fresh paint, but should I prime the whole car or just the damaged bits ?.
They say 2 coats of primer, should it be dry between coats, or do I spray one coat, wait 5mins and spray the next ?.
Does it need to be a fresh mixed batch for each priming coat, or do I mix enough for the whole job at once ?.
How much paint will I need for a complete car respray ?.
I would welcome any sugestions or hints.
