Welcome to the Forum, Jeffswed -
Hope you have lots of pads of each type to accomplish the work.
Have used Lake Country pads and backing plates for almost 20 years, and they work great..
The Hydro-Tech line, I renamed Hydro-Shreds, when they first came out, have proven to me to deliver outstanding correction, and finish down sometimes almost LSP ready.. I speak of the Cyan and Tangerine colors, and I use Rotary Power.
The hardest place to reach for me is the area under the door handles called the door cup. For this area, I have some white, cotton, soft towels that I use with 1 or 2 fingers and some compound to clean up that area just fine..
You do not want to try to clean up under there with a machine, because the -edge- of that door cup will not have as much paint on it (because it IS an edge), and it is possible to take too much paint off that edge..
Sometimes, I have cut up a used, foam pad to the shape I need as well..
They do make backing plates and pads down to 1 inch now, so perhaps, that may be an option..
The small, soft, white, cotton towel is for me, the easiest solution, for most small areas.. If you can get 1 finger in that spot with the towel, then, you should be good to go..
For smaller places yet, like the areas between letters, etc., a Q-tip -carefully- used can sometimes help, but you have to watch out because they -can- scratch, be rough, and create more work.. I try to keep the Q-tip very moist with the product..
Be innovative, think about it, and try to clean the area so it matches as best, the rest of the panel..
Good luck with this !
