I am currently using these products to clean up old model cars and promo model cars. They work great and restore the finishes of old paint and bare plastic! The scratch remover will help clear old yellowed clear plastic glass without causing any damage.

I used the # 2 to polish Tamiya spray lacquer to a high gloss after smoothing off the orange peel effect. Polished to a high gloss with not too much effort. The # 1 seems to be a lot like Armor All and I don't know how much it helps, at least on paint. Would buy the #2 again.

Excellent products. I use the number 2 Plastic Polish to not only polish up clear parts, but to also polish both Testers an Tamiya Spray Lacquers. I use the number 1 Cleaner to remove skin oil and give clarity to canopies and vehicles glass before gluing it into the bodies. After using te polish on finished I use the cleaner to remove all polish traces prior to waxing the finish. Always great results
