Very glossy product, sprays everywhere, but once let allowed to sit a couple minutes then wiped down leaves a nice black rich finish. I don't like the odor and make sure you have plenty of ventialation because the odor is strong. You can buy it at local auto part stores for about $4.99. I bought mine at Autozone for that in an aerosol can. I used it today to dress the engine of my Ranger and it does leave a beautiful finish. Just make sure to wipe it down after it has had a chance to sit for alittle if you don't like glossy finishes. Durabilty I dunno, also leaves a very smooth finish after wipe down but you have to do some light buffing to acheive the slickness, which doesn't bother me 1 bit. I'd say it's worth the weight of it's dollar so sto speak :up ,,,,,,,,91
