I've had so many 'first finish fails' that it aint funny. There was the one that broke free from the 'paint stick' supporting it after applying the final coats of clear... That dent sure didn't sand out. Scrapped that one. There was the one that had millions of tiny bubbles embedded in the finish. Extreme solvent pop. Stripped to bare and re finished it. One of the most frustrating fails was the one that kept getting these tiny flecks of white in the clear. After stripping and re doing a few times I realized that the paint cup liner on my brand new spray gun was coming off and contaminating the clear. Bugs in the finish far too many times to count. Elbow into the freshly sprayed finish a couple times. I've cut through with the buffer numerous times too. What makes me keep doing it? When one turns out like my avatar.
