the prep is the difficult part. if ur just going for a “meh” paintjob, its do-able. especially for someone with brains. just do it nice and evenly. As long as theres no drip marks and u done miss a ton of spots then u can most likely save it with a ton of wetsanding and polishing.
Of course I dont speak from experience, but ive spoken to a lot of ppl about it. It is my most likely course of action for paint.
