Kevin you need to use a primer under the Tamiya TS. Those scratches you are getting are definitely a result of your sanding. The TS is sinking as it dries and etching into the sanding marks that are in the plastic. Using a good primer will eliminate your problem. Also make sure you use a very fine wet and dry on both the plastic, before you prime and on the primer itself, before you paint. If you're leaving scratches like that in the plastic they will show every time without fail...

I'm confused..?? 100 grit, 320 grit..?? If you're using the same grit grades that we have in the UK then they are extremely harsh. I never use less than 1000 grit wet and dry for general plastic preparation. Sometimes slightly rougher sanding sticks if I'm rubbing down filled areas..
I also use TS lacquers for certain projects but I don't understand all the mist coats, waiting, more mist coats, further waiting, first wet coat etc. I just spray (over prepared Tamiya primer) one tack coat, 5-10 mins to tack off, then 2-3 wet coats with 5 mins flash off in between. Bake in the Mr Dry Booth for 60 mins followed by overnight drying, polish the next day.

If I'm in a rush it's Zero base coat colours over the same Tamiya primer. 2-3 light coats of colour with 5 mins flash off between, 20-30 mins in the Mr Dry Booth, followed by 1 light tack coat of Zero 2K clear, 5 mins flash off, then 2-3 wet coats of Zero 2K with 5 mins flash off between. Colour to clear, to finished, in under an hour. Baked for 60 mins, no polishing required, finish straight from the airbrush..
