I switch back and forth with my 1960 MGA with no issues. I know that 3 and 4 will eat paint but 5 will leave fish eye in the paint if it gets on the metal and then you paint and is very difficult to remove. I had my master cylinder leak and it was near an engine vent and the fluid blew onto the left front fender and no amount of washing would take it off. I know this has nothing to do with the current question but at one time it was not recommended to use Dot 5 in corvettes it made the brakes spongy.
