Today i was at a flea market not far from Buffalo NY.There was a guy there selling auto products.He had the usual sales pitch telling me his stuff was the cheap and the best you could buy.I started looking and reading the label of this car wax called GLO SHIELD.I then asked how it would work on a gelcoat finish? He said he had no idea,but if i wasrn’t satisfied he would be there every week and i could bring it back.I bought it for 7 dollars.It turned out to be the best wax i ever used ,and believe me I have tried many they all claim to be the best very few are.Dull areas shined and the car looked wet.Went to there web site they claim it will last 3 years.Price on computer is 9 dollars to 25 dollars Next week i will go to the flea market and buy more
