About Us

Mastercoat LLC was established in 1988 and is a small family business. Learn all about Mastercoat LLC.

We've been in business since 1988. Pat, the founder, started off selling a competitor's brand, and only sold the competitor's brand for one year. As someone who spent many years restoring cars, he was no longer satisfied with the quality of that product, and so, Mastercoat as we know it today was born. Pat is actually retired, but is still more than happy to speak to customers when advice is needed.

The answer is simple--we are a small family business and all of these things are very costly for a small business. We do advertise from time to time in smaller publications, but even that too can be costly. We even make all of our own videos. Since the day we established this business, our livelihood has depended largely on word of mouth from our customers. When you buy from us, you are supporting actual people and not a big corporation. We'd rather save the money from advertising and pass the savings on to the customer, so if you like our products, make sure you tell a friend!

No. We've been using the tagline "No more rust" as an identifier for our product line for nearly two decades. If the order of the words in the tagline are in any order but "No more rust" (ex: "Rust no more") and do not have the Mastercoat or Master Series Coating Line brand name, that is not us and not our products. Accept no imitations!

"Polyurethane" refers to the material type and the three coats are as follows: two coats of a rust sealer and one coat of a topcoat, like AG111 or Chassis Black Finish. Two coats of rust sealer and one coat of a topcoat create a barrier to stop rust and prevent it from coming through. You must ALWAYS use two coats of rust sealer, no matter what kind of surface you're working with. If you don't plan to topcoat, use three coats of rust sealer. Anything less will be ineffective.

Yes, we are closed on weekends, holidays (these include Memorial Day, July 4th, July 4th (observed), Labor Day, Black Friday, Thanksgiving, Christmas Eve day, Christmas day, New Years Eve day, and New Years Day). These are also the dates shipping is paused. There are weeks in May and July, and the week between Christmas Day and New Years Day that we are closed for shipping, and stock will not be released during these times. If you need immediate technical help with a product, you can still email or call us and leave a voicemail and we'll get back to you as soon as we are able to (even if we are closed).
