Haven't played the painted ones much. I do like Krylon Indoor/Outdoor White Primer better than the Rust-Oleum. A few light coats works best. Second pic is from the back. On coated heads less trouble to sand off logos. This was acetone on a Evans logo. They use a serious ink.
Next batch to do are really dirty heads. Hope 99 % iso alcohol will get most off then light wet sand.
