I am running out of degreaser (motor cleaner spray) and while looking to resupply I discovered that TA Emerald discontinued their Performance Plus 3 spray in favor of Performance Plus 4 earlier this year. I have a feeling the discontinuance of Plus 3 was due to this settlement with the California Air Resources Board.
Can anyone comment on Performance Plus 4, specifically 1) Does it work as well as Performance Plus 3; and 2) How does it smell?
I fear the change in formula forced by the settlement and new product offering (to lower the VOC concentration to fit withing the law) will make the product less effective (yet again). And I hope they didn't add a bitterant like Duratrax Power Shot which smells nasty.
