Ok is it a white car or silver...(I am sorry for answering this before dr. detail)...
well anyways...you want to start with claying...that is good...start with claying as completely strips the paint of all contamination and any previous wax coats...but then you do not have any wax layers from before hand...just follow the right procedure...and ofcourse it should be done after a rinse and shampoo...
Now is your turtle gloss the final coat one...the one in a dark green bottle...if that is the one...put it on the side as you have mothers step 3 which is a similar product.
If you wanna keep it within the arsenal you have...after the claying procedure...apply speed and then seal it with mothers step 3...you can stop here as well...but I being a fan of nauba over synthetic will recommend putting an additional coat of nauba over the sealent to add even more depth to the sealant.
a week or two week later when you believe the coats are wearing off..you can repeat the waxing process...replace the mothers with the turtle gloss and compare the results...
however, if your turtle gloss is more on the glaze side rather than a top coat...you can apply it between claying and speed stages...Infact send a PM to amir@accord...as he uses speed nauba as a glaze...find out the technique and maybe you can do a speed glaze, followed by step 3 to seal it and then a full nauba speed coat for depth...
hope this helps
