Hello. Is there a national equivalent for Kontakt 61/40?
Are they only in the original for protection?
Ps. Does 40 really have a lower impact on the resistance and does it work better outside and in the car?
Maybe someone has also tested petroleum jelly in a spray up to 120 ° C as a protection against Kontakt 61?
