How careful do we have to be about the E30's paint when choosing a detailer? Do they need any special expertise handling our cars? Can a competent detailer using a typical protocol damage the paint?
As a general statement, paints have become more durable in recent years. However, the tendency to rely on power tools to save labor does increase the risk of damage. If the job is done by hand, there's very little risk of damage. There is always the possibility of burnt paint with a power buffer. It's a tradeoff. A good hand job may cost you 4-5 hours of labor. A job with a power buffer may cost you an hour's labor. You get what you pay for,
I agree with John that you get what you pay for, but a good machine job should still take about 2-2.5 hours. There should still be some hand work involved as finish work, but when done right, the power buffer does an amazing job. Just my 2 cents.
