If You Think POR15 is Good Paint... Watch This Video! Paint Testing Eastwood, KBS, POR15, and More.

In this comprehensive video, join me on an in-depth exploration as I put several rust encapsulating paints to the ultimate test. I've carefully selected a lineup that includes renowned brands such as POR 15, KBS, Eastwood Rust Encapsulator Platinum, Bill Hirsch Miracle Paint, Rustoleum Oil Based Enamel, Raptor Liner, and Mastercoat.

My rigorous examination spans across six critical categories: adhesion, chip resistance, flexibility, UV resistance, corrosion resistance, and chemical resistance. The extensive testing process unfolded over an 8-month period, allowing each paint to undergo the necessary UV exposure and, in some cases, pushed to failure within a salt fog cabinet.

Contrary to popular internet opinions, I aim to challenge the status quo by revealing that there are superior paints on the market compared to the widely praised POR15. Through this detailed analysis, my goal is to empower you with the knowledge needed to make an informed decision when selecting the perfect paint for your specific project.

Each time you put out a Video concerning metal protection, I get way more excited than a person should. I’m not sure anyone else is as committed as you are on doing these long term tests. I very much appreciate the amount of Time, Money, Energy and Thought you put into these tests. Great thorough job!!

As someone who has fought rust, living in Connecticut for far too long. I am grateful that you put this video together. Ive experimented and wasted a lot of hard work. This is gonna save me so much money in the long run.

You and Project Farm are my go-to’s for thorough product testing. Thank you for what you do.

Interesting video. I have tried all those products. Been restoring cars for 46 years and find overall Rustoleum "Rusty Metal Primer" top-coated with Rustoleum paint, which is the longest lasting and is the cheapest product out there to use, for what I use it for. I used Por15 once and never again, as the car I used it on, I had to re-restore all the components the Por15 was used on within five years. Por15 is the perfect name as the product is very poor and 15 times the cost of other products.

I performed chemical comparability and environmental testing for the auto industy for years, and i am very impressed with your methodology and analysis. You are worlds ahead in actual test methods and data collections than almost all the big youtube "test" channels.

There are some parts of your test methods you could improve, but you definitely got the core data and you did it without an industry testing sized budget. I am very impressed and just shot you a sub. Cant wait to scroll through your back catalog snd see what you have coming out next.

Used POR15 heavily in the early 2000’s. Prepped exactly like they wanted. Used their metal prep and everything. Removed all scale and dirt. Only surface rust. In less than a year, it was peeling off in sheets. Rust had traveled under the coating, kind of like powder coating once it’s scratched. Now I clean and prep down to only surface rust, spray with Duplicolor Rust Fix rust converter and top with either Eastwood Rust Encapsulator or Zero Rust. Sometimes I will top coat that with Eastwood Extreme Chassis Black. If I can sandblast down to bare metal, I will prime with Duplicolor self etching primer and paint with Seymour MRO high solids enamel. Sandblasted engine parts get Duplicolor high temp engine primer and engine enamel. Have been pleased with their performance. All of them.

I have used POR15 and I agree with the test results for POR15.
I found that POR15 worked better as a rubber/fabric cement than a paint.
The first time I washed the dirt from the under side of the car, It came off in notebook size sheets.
I tried every kind of prep to get it to stay and it failed every time.
Sticks to your skin real good though.

I've been preaching this for well over 20 years. Master Series is a great material and I use in in Restorations and have for a long long time.

The first time I used Por15 was 2008 and I was amazed at the results. Fast forward to 2023 and I found myself buying and using it again. I noticed the consistency and finish have changed. The changed has curbed my enthusiasm for the product

I am so happy to have seen this video before tackling my 2000 Tundra (The RUST King!!). I've been holding on to Por15 while I gathered remaining parts and supplies. I IMMEDIATELY went to Master Coat site and they are sold out die to the high demand from YOUR VIDEO!! That's awesome and a bummer at the same time. Keep up the good work and thank you!!

DUDE!!!! Great video! Being a DIY'er, the thing that sucks the most is spending time, money, and stress in a project and watching it fail. You have giving us a view into a controlled failure so us DIY'ers can make intelligent informed decisions as to what products actually hold up in certain situations! Thank you as a fellow Northeast Ohioian! Now I know what I'm going to use on my 72 Monte!

HOMEWORK.

I appreciate your service and your straight up blunt comments on bad products. Thank you

Almost 30 odd years ago when I was restoring cars Por15 was the stuff to use and other than wire brushing loose material off there was no surface prep needed and it worked great. From my understanding they were bought as a company from the original owner and now the quality is what you have today.

Dude, 74 yrs old here, mechanic, and engineer - - and have tried just about everything. You have done an outstanding, fantastic, job of comparing the products. Most I don't know but POR15 I do. You are exactly correct - it is crap. A '77 C10 all over rework in '96 and the frame has just kept pealing. Worse, is that the sheeting you mentioned makes rust much worse. This is a million dollar test series, literally! One thing - - primers. It would be fantastic to see a zinc chromate and/or strontium chromate primer tested with some of the other topcoats. They are hard to get now, but DoD scratch testing shows outstanding results, although the reports are not as complete as yours. The USArmy has some good specs for equipment that gets shipped (literally) and then sits a long time in various climates.

WELL DONE!!

I have used Rust-Oleum for decades and did so because of price, availability and ease of use, but I always wondered how it stacked up against other more expensive coatings. Now I know. Many thanks!

A huge amount of work has been done. For which I am very grateful. I was recommended POR-15 and I already wanted to buy it. Thanks to your experts, my opinion has changed, as they say, it is better to see something once than to hear something once.

I've honestly always used por15, just wire wheeled the parts(usually suspension items, drums, backing plates, trunk floors ect) cleaned them with brake clean and brushed it on. But seeing how well Mastercraft worked for the same price I think I'm going to have to change my product. Thanks for your hard work on this video I appreciate it.

Paint surface preparations is the most important .. Acetone Clean and the specified roughness of the sub straight must be present in the moment of application and conditions that the paint was intended for to cure .. Paint is tested in a 100% controlled environment. Stable .. Humidity ... Stable Temp... I have been testing paints in the field my whole life.. What ever the pockets of the project can handle .. The Paint can out cost the item being coated fast becoming the most expensive phase of construction.. Keep fixing stuff .. read the manual of the products cost and application parameters to match the job the closest matching product always .. good job keep testing Yong man putting metal rims on your cars to do tests on them is a vary good way to test exterior products in a real time full exposure level. Try the same test with a high quality epoxy two part primer white ... then sand parts then spray all products at same viscosity build up the same dried thickness and retest .. in this case the spray paint can may be the lowest viscosity.. Find the Thinners .. in them all .. do the research.. Paint is a vary complex world of coating options ... I work in the marine ocean environment vessels all systems and shore line building construction and upkeep in the tropics.. Its all about the paint Keeps us busy 24-7-365... good luck too you and have the best year.

My go-to for quick and dirty rust protection is Rustoleum Hammered. This type of paint doesn't need primer, just wire brush the loose stuff. It's tough too.
