I agree whole heartedly and that's why I choose not to go that route. A.I. offers this process as an A.I Series Special and all it is is a little paint and polishing,nothing is done to the inside of the motor! it's all cosmetics,that's all and believe it or not it does help sell engines. Cactus will also do it if it is requested,but does not push the issue to help sell motors under the Cactus Series name!
My advice to anyone looking to buy the upgraded QS Series regardless of who you buy from A.I. or Cactus, ask questions on the paint process!! and not from just one person, make sure to get a second opinion it always helps.
