Great product

I'm very pleased with using this product. I am by now means a professional but am repainting my Jeep Comanche pickup. It's a zebra design- I did the original myself with spraycan & masking tape. This time I am hand-painting it. This product is far superior to using a spray.

20+ year customer (recent order)

Everything came in a timely fashion. The only issue with shipping was the alloy bottles were leaking. Other than that everything was nice and sealed. Coating works as it should. I do like the assortment of colors, that is a nice feature.

I have used this stuff for mor than 15 years - works grea

Great stuff have tried other brands of rust converter and have always come back to por15. Several times I have redone a project for better results

Love the Product, Hate the packaging.

I have been using POR-15 products for many years with great results. My complaints are with the way that the product is packaged and shipped. I have encountered multiple quart cans over the years in which the lid is impossible to remove without damaging it to the point that the can cannot be resealed. This results in the remaining product hardening up in the can. I have also had several occurrences where multiple cans were shipped in a large box without proper packaging. The cans arrive severely dented which can also make them difficult to reseal. In one case one of the cans was leaking to the point where it soaked through the box. Please pay more attention to the packaging processes. Thank you.

Than you for you input. We have brought this up to our quality control in shipping. Unfortunately sometimes the carriers will repack our shipment if they damaged the boxes we send. When this happens we don't have any control over or knowledge of it.
