To use or not use DOT5 fluid?

not good on a street car ?????? wow i didnt know that since i ran it for 28 years in the same car same rear wheel cylinders and lines,,, it is A perfect choice for a performance car,,,it doest attract water never rots your brake lines,,,as said if it gets on any painted items it wont take the paint off like dot 3 or 4 will,,,,its well worth the extra cost,,,

replace the master,,,blow out the lines and the wheel cylinders and make sure the calipers are clear of old dot 3 or 4,,,you will thank your self 10 years from now,,,,
