NOTE: Japanese-made urushi causes stronger allergic reactions than standard urushi. For this reason, it is likely to cause a serious rash & other symptoms, especially in individuals with weakened immune systems. Please refrain from using this urushi unless you know that you are urushi tolerant. If you feel something unusual after the urushi application, you should visit a dermatologist.
Substitute of this kind is UM0203 "Low Allergy Urushi Lacquer, Raw 100g"
It is also known in Japan that any natural whetstone's backside needs to be reinforced with Urushi paintings. RAW (Seshime) Urushi is applied for this purposes.
Depending on how much strength you want, 3--10 painting are normally required.
Please remember, one Urushi lacquring takes 4--7 days to dry in a drying cabinet called "Muro," so this can be a long process.
