Nathan, i usually dry the car with G&G, clay and then use the paint sealant with a swirl killer. Like i said i only use the G&G to aid with drying, i leave it to the paint sealant to protect the paint and throw some buttery wax on top of that to enhance the shine a bit.
Should i just start using detail spray to help aid with drying rather than G&G? since a) im using paint sealant again after claying, and the clay could take the G&G off making it pointless
