bhai jan the products and process u done is more than a beginner Mashallah results are good 
Trizact leave tracer if used with rotary so next time use with hands or it also comes good with DA polisher
next time use water moist Trizact with hands and with very very less hand presure and in straight strocks , less presure and more strocks will remove tracers and will put very minor new tracer , since paint is new so even ultimate compound will give u very good outcomes inshallah
Respect your passion and your work really
