How can I stop Red PETG from being too Transparent on a Top Surface? (lemmy.blahaj.zone)

I'm working on a Project that Prominently Features a Red PETG Top Surface that after the Printing is done gets Sanded with Grits from 400-2000 +Heat Treatment.

There is a Big Issue tho, After the Sanding is done, I can Rather Prominently see the Walls and Infill of the Layers Below. At first I suspected that I just sanded too much and that the internals weren't really filled in 100% as they should, but after some testing and Closer Inspection, it just seems the Red PETG is just Transparent enough that I can see the layer below...

So how do I stop this from Happening? Thus Far I played around with Fan Speeds, Nozzle Temps (±10°C), Layer Hight and Ironing all Solid Layers with Mixed Success, non Satisfactory enough however...

Yes, top layer is set to 5 layers yet it only does 1 Top Layer since thats the surface. Rest is handled as Infill.

I tried everything from 1-100 Top Layers, nothing changes. Insides still get printed as Regular Infill.

Can you please upload some screenshots of the model you're printing in the slicer, and the related settings? That's really odd behavior.
