This stuff is amazing. Starts working within a minute. Use glove and a mask. Tried other strippers with nothing but frustration. You get what you pay for. Im close to Aircraft Spruce, so no shipping cost.

This is old school type stripper, good ventilation and PPE is a must. It does seem to work like the old stuff which is mostly good. If you are stripping a 1970s vintage Piper with original paint, this is NOT your material to use. That Acrylic whatever paint they used does not strip well with this product.

Store bought stripper was ineffective. Tried PTI to get stubborn primer/paint removed around rivet heads. Worked great -- applied the remover, let it set a few minutes, agitated with a brush and the crud dissolved. Wish I had tried this product sooner. Very happy with results.

Works very well against polyurethane paints. With the consumer ban on methylene chloride strippers, none of the OTS strippers in hardware stores work anymore since 2019. This PTI stripper however continues to do its job well.

After trying several different paint strippers, all of which were found to be utterly useless, I purchased this and was pleasantly amazed at how well it works. Once applied, the pain will begin to blister and loosen within a few minutes. Used this product to remove old glue while replacing carpet in my plane. Again the results were amazing. This product actually works! Highly recommend this product.

I first found your site when looking for a polyurethane and epoxy remover. For years I had been using products that a person would get at a local concrete bldg store and I wont mention the likes of names. We all know that such products have been removed and the ingredients have changed to the point they are useless. So with that being said I searched and searched and after buying a few products from the local hardware store I had almost given up. And certainly was reluctant to spend a lot of money to experiment with any more products from a hardware store. In my search I found Aircraft Spruce green PTI paint and polyurethane epoxy remover. I have to say for a person that has been using strippers for many years I was skeptical. I thought why not just get a quart and see if it really works. And so for any potential customers reading my review I want you to be confident that it truly works and does the job. I have read some of the reviews on this product and see there are a few that are negative. So with that being said I first must say you have to know how to use a product that is made for stripping. Tools needed for doing your stripping job Temperature is key. Gloves! Throw away paint brushes or a person can use a quality paint brush and wash it out. This product cleans up very well. Eye protection! One thing I will say about the temperature when it comes to stripping it depends on the item your stripping. Ive used this product on many items now and it reacts a bit different depending on what your removing. So one must experiment a bit. Clean up items needed Rags buy yourself a bag of rags from the local brick and mortar store. They are cheap and you can just throw them away. At least that is what I do. If your working on a big project you will have to strip small areas , dont let your project get ahead of if you. There are however a few tools that are needed that you can not buy. 1. Patience 2.The Will to preserve 3.Experiment and you will gain experience. 4. Safety 5. Acetone Aircraft Spruce has it available. 6.Know that this product will help you achieve your goal. With all this being said I cant thank Aircraft Spruce enough for having a product that is satisfying to use. Its safe and does the job. Ive used it on wood and on metal and even on glass Thank you so very much for your product. I would not be able to do my job without it. Your appreciated

Low odor, works fast, well, and doesnt harm aluminum. I stripped factory glue residue from my entire interior cabin and firewall. Also stripped epoxy paint from individual airframe parts. Good stuff. Burns on contact with skin so must wear gloves.
