I'm a big fan of over the counter products, that being said I use Meguiar’s products. One of the best steps you can do it to clay bar your Nitro after a wash. This will remove all of the surface contaminates on the surface of the paint followed by a wax. This is the easy process, if you wanted to do a full process there are other steps and products you would need to use. For the interior I like to use Gold Class Vinyl/ Rubber. For all of the exterior plastic use Trim Detailer this stuff is easy to use and works great.
