Easy way to detail in the wheel wells. Been using for years and I always buy it by the gallon.This product works as described. After cleaning my wheel wells with a brush and wheel cleaner, applying this dressing in two separate coats produced a nice black shine that makes the area look brand new. One coat showed plenty of runs after drying, but two coats evened out the finish. However, this dressing will leave behind a film wherever it drips. I placed some cardboard under the front and back of the wheel wells to catch dripping while the product dried. The dressing also appears to dry rather than staying greasy as a tire shine would when used for the same purpose. The only negative is that the spray mist is rather fine, which means this dressing will get airborne and land on wheels and fenders - but a quick detailer will take the overspray right off. Overall, I recommend this product.Very good product make a difference in appearanceOutstanding!!!!!Griots has numerous products for which they really ought to be lauded and recommended.As a professional Auto Detailer (who has spent, and therefore blown, THOUSANDS of dollars testing products), I simply cannot do without This stuff get the job done. I've had it in my garage for some time and it does work. If you move your hand while depressing the spray nozzle, it can cover a decent amount of your undercarriage. It's more fluid then thick which helps with longevity. It's got a scent to it... as long as you're in an open space, you should be fine. You've got to have a serious spray bottle on hand to use this stuff, too. If not, it'll go right through your Dollar Tree bottle(s) in a heartbeat! Get a professional-type spray bottle/nozzle and you shouldn't have any problems with it.I don’t know what the deal is with their spray nozzles but this is the second bottle in a row where a small metal ball falls down the draw into the bottom of the bottle and the spray nozzles stops working. Very aggravating!This product is easy to use with the nice spray tip that comes with it. It covers a lot with each spray stroke. Made my wheelwells look nice & black. Also went underneath and sprayed what's exposed.I was on my concrete driveway, so when I finished, I drove my van into the street, and just hosed off the drippings left on the driveway. Product left no discoloring at all. Actually made it look cleaner.This stuff works very well and gives your undercarriage a nicer finish.Nozzle didn't work from the beginning. Poured it in another sprayer. Nothing impressive. Wouldn't recommend.
