RM/Glassurit are good paint but they are more for factory refinishing (same color factory paint jobs)in my own opinion. RM/Glassurit is great for doing blends. I prefer Sikkins or Dupont and Valspar. I have been painting for a while and i have used just about every kind of paint. RM/Glassurit, Valspar, Xotic, Dupont, Sikkins, House of Kolor, Nason, and i am sure there has been a couple more. Besides Nason being just cheap ass colored water the rest of the paint brands are a lot alike. The only difference is how they cover. Like Valspar or RM it might take 3-4 coats of base to achieve desired color. With Sikkins it might only take 2-3 coats to achieve desire color. But with Valspar and RM at $35-60 a quart. Sikkins and Dupont is more like $60-95 a quart. House of Kolor is made by valspar only difference is house of kolor has Kandies, Pearls, flakes all the cool colors. Same as Xotic which is a HOK copy. Regarding the price if you take it to a body shop he is right it will be more expensive because they have overhead, employees, and so on. If you go to a local paint store and ask them if they know any body that paints cars. I have been painting for about 4 years and my complete paint jobs are under $2000 include color sanding and buffing. I do agree stay about from single stage paint if possible. 2 stage or 3 stage is by far better becuase you can sand down the clear coat for scratches, blems, and so on.
