i have been a painter for 40 years. i dont do it as a hobby. lacquer is one of the hardest paints to use properly. it is also misused by most people who use it. people use it because they cant paint and think it wont run or sag so it must be easier. wrong. it is to be applied wet and thin. just about every home job done in lacquer will have a life of about a year. then it will check and have to be removed. any solvent will soak into and lift it including gas.
just for the record if you have to sand and buff lacquer you did it wrong.
