A. Dear sir,
The double rub test should be okay for this. Soak a cotton cloth with petrol, vigorously rub over the cured coating several times. Rubbing twice is a double rub. Calculate the number of double rubs required to soften the coating. Normally 50 double rubs is a pass. If you put stringent Quality control, then 200 double rubs may be okay.
