I use the slip on's with my ram sport(painted mirrors) I use th foam tape supplied, wax with a quick spray on wax ahead of time and cover the painted part of the mirror with a shop quality paper towel.. No scratches or scuffs in 2 years so far...
I opted not to get tow mirrors when I bought my truck because dodge doesn't offer the "power fold option" with the tow mirrors.. I tow my trailer 5-10 times a year so the slip ons are good enough for that. Driving daily in the city, it's nice not to have the larger tow mirrors...
