It might have beared it, being 1st time (although I think some damage might have been done even for 1st time), however, for 2nd time, and onwards, Cat. Conv. might fail altogether.
Next time, either use Liqui Moly Cat. Conv. Cleaner, or go to Motor Clean.
Proficar Cat. Conv. Cleaner does not prove effective in JDMs, and I am saying it based on my personal experience in Passo.
