Tamiya Polishing Wax

I have completed the final paint coat on my VW Beetle.

I am thinking of the following remaning steps:
a) Polish with Tamiya rubbing compound to a shine
b) Decals
c) Spray with Gunze's Top Coat (Gloss)
d) Polish with Tamiya rubbing compound to a shine
e) Polish with Tamiya polishing wax

I was thinking of omitting the application of Gunze's Top Coat (parts c and d).

Questions:
1. Will Tamiya Polishing Wax react or affect the decals if directly applied on without a layer of clear coat?
2. Does the polishing wax protect the decals from yellowing?
3. Even if I use Gunze's Top Coat, is it compatible with the base paint which was sprayed with Tamiya Lacquer Spray Can? ("compatible" as in no chemical reactions)

1.) It won't affect the decals.
2.) Yes
3.) If the color coat was allowed to gas out for a sufficient time, nope. Make sure to start out with light coats anyway, if you apply too much you might remelt the color coat.

Wax is not a polish. The two are totally different. A polish is a fine abrasive used to remove scratches and level out the surface. Wax, on the other hand, is a organic or synthetic substance that adds a layer of protection and shine. :)

Thank you for the advices.

Also it's important what kind of paint you are going to use. If it's metallic, please don't polish it with compound. Leave it alone. If you're that much after a perfect surface both under and over the decals why not give the model a few coats of clear, polish those, add decals, then some more coats of clear and then polish it again. And then wax it :) But be careful as the margin for error is not big when you're polishing clear that was sprayed over the decals.
