I recently completed (except for windscreen) this build for an upcoming proxy for 1.5 liter 1960's Grand Prix cars.  The resin shell (Pre-Wing) has been finished with Tamiya rattle can primer, color coat, and top coat.  My questions are:

1. Can Tamiya's "Finishing" polishing compound be used over top coated decals?

2. Is Tamiya's "Modeling Wax" a better product to use over top coated decals?

3. Can you recommend any other products?

Hi Bob, Any of Tamiya's polishing compounds can be used over their gloss paints or gloss/semi gloss clear topcoats.....they are formulated for this, and work without any issues........I have used them on many models, and recommend them highly.

Their modelling wax is excellent, and can also be used, either on uncoated or coated decals, but, if used without a clear top coat, it will not provide the protection generally need for a slotcar,.....particularly one entered in a proxy 

My recommendation (if your finish is smooth)  would be to use the "fine" and "finish" compounds only.......you will get a gorgeous finish !!
