Adam's Polishes Paint Sealant vs Chemical Guys Jet Seal Sealant & Paint Protectant

Adam's states a six to nine month range rather than a ceiling and is the only product here that tells you where it belongs in a layering order. Jet Seal claims the longer period at up to 12 months and costs less, and you have to read the bottle rather than the website to find that out.

The only sealant here that says how long it lasts, and it tells you where it goes in the layering order.

• Six to nine months of protection claimed on paint, wheels and other painted exterior surfaces, the only durability window in this comparison.
• UV blockers stated as maintaining gloss, shine and reflective properties, which is the mechanism that keeps paint from dulling.
• Applies by hand or machine, so it suits both a weekend job and a full correction.
• The brand states it should go on before waxes or glazes to bond with the clear coat, which is layering guidance nobody else gives.

• Thermo-Resin Technology is a brand term rather than a chemistry anyone can evaluate.
• No cure time published, which matters because a sealant needs to be dry before it meets rain.
• Grey colour and a heavy coconut fragrance, on a product you spread across an entire car.

Claims up to 12 months and advanced UV protection, both printed on the bottle and neither on the web page.

• The bottle states up to 12 months of protection, the longest duration claimed by anything in this comparison.
• Advanced UV protection and hydrophobic properties are listed on the label, alongside nano-tech polymers as the named chemistry.
• Developed for airplane exteriors, which is a genuine indication of how it was designed to handle UV, temperature swings and speed.
• Cheaper than the cream sealant it competes with, and widely stocked.

• None of the durability or UV claims appear in the online product description, only on the bottle.
• Up to 12 months is a ceiling rather than a range, so it sets no expectation for a normal car in normal weather.
• Sold in a single 16 ounce size.
