I highly recommend this shampoo Recommend to anyone. Have previously a Sonax shampoo used here, however, the disadvantage that are worn all waxes or sealers (good for a resealing). The Gold Class of Meguiars here has the great advantage that no wax is washed away, so that the sealing of the vehicle remains in good condition. It is very rewarding for a reasonable price! So a strong buy recommendation from me.
