Just washed and waxed the Celica today as well.
Hose off the car followed by Optimum no rinse wash in small sections so it doesn't dry.
I have been using Finish Kare 2685 Wax for a few years after getting come containers really cheap. It goes on super smooth and I buff it once with a denser Microfiber and follow it up with a lighter Microfiber to get it super smooth. It's a good wax for the money and I have two of these containers which look like they will last forever as it's very minimal application with how well the product spreads. Has a great reflective finish that I like. A few reviews have people using it on dark cars with good results as well. I've layered it over Finish Kare Sealant in the past and both products held up very well last year when I did it. Not sure how respected their products are but they seem to have worked well in taking care of my Celica.

Not bad for 15 year old daily driver that spent half it's life ungaraged. Of course I am gonna miss taking car of a silver car.
