I guess Amazon doesn’t handle their products with care anymore. Can’t return/replace because it’s an aerosol product. The product itself is great but the shipping & handling is terrible.

Went on well like others have said. Kindof bubbles up to create some texture so plan on multiple thin coats for the best results. Also plan on buying more than you think. It took two cans to do one wheel well

Penray is by far the best undercoating I've tried. I originally used 3m and didn't like the texture, so i switched to this stuff. I top coated over POR 15 and the coverage is nice and even with a matte black finsh. Like any paint project, prep is the most important step. If you take the time to do it right, this stuff will produce an exceptional finish.

This product was pretty good. It needs multiple layers to do the job, and several days to finish it properly according to the can. I would also but double of what i initially thought i needed to make those multiple coats. Instead I added flex-seal as a final coating.

No clumping. Several more expensive brands seem to clump more and drip. This brand went on smoothly like paint without clumping or dripping. I placed plastic under the vehicle just in case but the splatter was very minimal. Seems to be a quality product. Great price for an excellent product.

Used it to undercoat my 08 Chevy Colorado. Dried quicker than I was expecting and sprayed on nicely. Just have to see if it can hold up through a New England winter before giving it 5 stars.

Wonderful price for a case and it stays on better than rustolium or 3m. It stinks. Make sure you don't spray it on areas where it gets hot.I also coated a toolbox I repaired and it looks great. Stinks up the car though.Buy it!!
