Personally I'd wet sand that back and reshoot the TS17.
...Which is what i did with my Pug 206 yesterday - wet sanded the TS30, added two coats and then did two mist coats of TS13 with airbrush and 30 mins later two wet coats of TS13 from the can.
Here's how mine turned out...
TS30 does darken under lacquer - so if you want more brighter silver go for the Mica..it should look good after polishing.
Now we wait to see what happens...
