No offense, but Lacquer? Wow, who turned the time machine back 50 years? You might need a new paint supplier. That price is wayyyyyyy out there too.
I just got a quote for a quart of GB5 blue and a gallon of clear with all the neccessary reducers & hardeners. Around $130. I'm just doing the engine bay for now. This is for base/clear. A quart of single stage blue was around $30, plus reducer. I was told hardener is not needed, but recommended.
This was at my local NAPA. I forget the brand of paint.
My paint guy mentioned lacquer only when speaking of his days as a painter MANY years ago.
