Works Great on the Cessna tar that has been in place for over 60 years. True labor saver....

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
