Takes off adhesive and black tar with minimal effort. 100% worth it.

This stuff works!!! Brush it on, wait 10 minutes and scrape of the old adhesive. I used this to clean all the old glue from the floor boards on the interior of my 1976 Piper Arrow as I worked my way through the refurbishment of the interior. It made a real crappy job much more tolerable and saved me a ton of time. Well worth the cost.

Perco 321 is awesome. We removed the adhesive on our wings and it only took 1 hour. Just glop it on and 10 min later scrape it off with a plastic scraper. Comes off like butter. We’ve told all our friends! Huge time and energy saver.

Did a nice job of removing old adhesive (1300L) from the wings in preparation for new boots. Doesn’t have an unpleasant chemical odor like most solvents, but the orange aroma can get a little nauseating over time, especially in poorly ventilated areas. Overall good product would buy again.

I don’t usually review stuff as I buy stuff from Spruce all the time. This stuff actually works, it’s expensive, but when you consider how much time you’ll save... it doesn’t eat paint, it just emulsifies glue/adhesive’s.

Works great ! orange peel smell and remove fast boots and 1300l I have ever rinsed off with water but lite scrapping is more like it
