The biggest problem that I have seen with them has been color match. Most of them come out to light. If you can get them to match color you should be OK
Color matches are off for most of the major suppliers in the last decade or so due to trying to simplify the computer mix programs, this means reducing or eliminating ALTs, or combining the ALTs for a single formula, or the merging of paint formulas that were used by several different auto mfgs, past and/or present into a single formula for the consumer
