In general, the patch method can be very reliable. The main thing is to do it correctly. Measure the maximum depth of the puncture and write it down on the outside of your motorcycle tyres. Knowing the thickness of the rubber layer will help you apply the vulcanizer correctly in your future work.
Then, using a special vacuum cleaner, remove the rubber dust from the area you have treated previously. Apply a degreasing liquid to the cloth and wipe the defect, moving from the center to the edges of the repaired area. Wait 3-4 minutes until the surface is completely dry.
Then mark the damage with special marking chalk and apply to cure adhesive to the treated area.
