seems like you have the material to practice. use the side door or the hood of the shell to get used to the gun. just move your arm before you spray the gun and release it before you stop the stroke, youll get it its not to hard for a decent job. the 10/10 rule will get it done but get some practice the more you spray it thinner like that youll get dust in the spray really easy and it will get the paint gritty. So id say spray it one good time or two semi fast times, then light sand, spray again, check it for dirt and trash. then spray your clear 2xs, and check that possible sand lightly, spray again........take pics before and after
