Paint - Repairing Base Coat

1)The run is in the base.
2)Not metallic paint............just plain white.........when finished, car will be all white with a red bumble bee stripe. Nothing fancy, just a 318 grocery getter.
3)I have lots of time to get this done, think I'll paint one side at a time, giving it two to three days drying time before I flip it to paint the other side. The light in my shop is not all that great, so laying it flat should help me see better also.

Thanks for all the tips..........no more excuses............I'll get started tomorrow. My overall goal is to get the complete car painted before cold weather, since my shop is not heated.............jas
