Well, if you want to keep your ride for a more extended period, you should take steps to prevent rust. However, for people who frequently change their vehicles, such a worry is not necessary. People typically wish their vehicles to last longer; hence, rust coating seems like a sensible investment for long-term maintenance.
Por 15 rust prevention coating is nonporous and provides a seal and protection from chemicals, water, and salt. Moreover, it is suitable for painting over rust, corrosion, and other contaminants. The Rustoleum brand creates very durable spray paint, which also is available in cans and is ideal for applying to autos.
Por 15 Vs Rustoleum: which is better between them? You don’t have to worry about that. Continue reading below to find out overall each of them.
Por 15 Vs Rustoleum: Comparison Table
Let’s look at a comparison chart between POR 15 and Rustoleum. Once you have read it, we can move on to the discussion.
|Water based||Oil based|
|Requires 2 coats||Requires 1-2 coats|
|Durable for over 4 years||Durable for over 5-10 years|
|Approximately 50 bucks per quart||Approximately 10 bucks per quart|
|UV intolerant||UV tolerant|
|Needs proper prep||Priming with red oxide|
Detailed Comparison Between Por 15 vs. Rustoleum
In terms of its formula, POR 15 is water-based. It primarily works with preparation schemes. Additionally, it has metal etching capabilities. Moreover, it is free of toxic elements, non-caustic, doesn’t allow corrosion, as well as non-flammable.
Por-15 is basically designed to detect moisture presence & quickly dry. Therefore, it forms a seal. Por-15 prevents metal deterioration due to any ingredient.
Rustoleum previously contained whale oil in its formulation. But now you can’t find it. Instead, you can use alkyds, epoxies, latex, and polyurethane. All of these yield resin, which can be used in formulations. Rust-Oleum works better than any other air-drying enamel product.
Both are the best formulizing products, but Por 15 wins. POR 15 holds moisture better than any single component primer and also contains iso-cyanates. Whenever you use it, wear a respirator.
UV intolerance is POR 15’s biggest issue. This approach may not be helpful for areas that remain under direct sunlight for a long time. After a few days, discoloration may occur. In this case, a top coat may help. POR-15’s performance as an electrical conductor is generally poor. Therefore, powder coating over them would just make sense. The IRS differential, metal segments, as well as other suspension components are excellent.
However, Rustoleum is used on farm equipment, because Rust-Oleum is actually not designed for use on vehicles. Therefore, when it is applied to vehicles, fading will occur more quickly. Rusts will begin to appear once again. Rusty metal primer comes in handy in this case, since it holds the paint well.
POR 15 is the clear winner in the performance category. Most of the time, they work well for early rust presentations. Por-15 has a higher performance rating than Rustoleum.
3. Coatings Process
As a general rule of coating, POR 15 should be applied in two coats. The 1st coat should still be tacky but at least almost dry, so it’s best to apply the 2nd coat immediately after.
In contrast, Rust-Oleum requires only one coat to work. Whenever a color other than white is used, only 1 coat is necessary. In contrast, 2 coats work best for white shades. Someone may now apply another coat if they wish. It’s best to wait 6 hours between two coats. Otherwise, the 1st coat will come off, and then the second coat will sit poorly as well.
The winner here is Rustoleum at first glance. It only requires one coat, so it’s quite better compared to POR 15. Remember, the real measurement will be how well they perform after applying.
4. Application Process
If we are talking of POR-15, the product should be used on rough surfaces. As a result, the product is able to grip easily since it is not affected by rust but instead grips it. People certainly think twice before applying, and they make sure the surface is clean and shiny. Sadly, they don’t do that here.
When you do this, Por 15 will not adhere properly, not even after sandblasting. That is why some people refer to Por 15 as painted over rust. Consider using powder coating or urethane paint. They will be more durable.
Applying Rustoleum is easier compared to Por 15, but sometimes it does not produce the results expected. As a result, depending on the surface condition, different results can be achieved. Rust-Oleum can be frozen in a normal fridge overnight, according to some. In doing so, the paint will be able to reach the surface before it has hardened. However, this is not a good option for frames. Using a primer will allow the paint to bond better. Spray the paint from the suggested distance, making sure you move the can from right to left and up and down.
POR 15 is the clear winner for a variety of reasons. In terms of materials hardness, POR 15 is fantastic and there will be no chemical connection.
Por 15 Longevity may flake off on some surfaces. Even after curing, paint doesn’t adhere to it. Whether it’s still there, simply healing it would last virtually indefinitely. And it frequently lasts for almost 4 years.
Rustoleum, on the other hand, has a good reputation for lasting 5-10 years, and even in most cases, even longer. Whenever you use this to the back axle, for example, you may expect it to last a long time. Nevertheless, In the matter of framing, it’ll almost certainly be a mishap.
The winner in the lifespan category is POR 15, which would also function well below the automobile. If you choose the correct application, you may be able to keep it in position for nearly 10 years.
Por 15 Vs Rustoleum: Which One Is Better?
Which would be the better choice between Por 15 Vs Rustoleum? The Por-15 does not react with rust, and it needs rough surfaces in order to grip. Smooth, shiny metal won’t stick to it. Although sandblasted metal is pretty good, it isn’t ideal.
With Rustoleum, make sure to prime with red oxide, & everything else should be fine. If you use the primer, it should last quite a while; plus, you can use a semi-gloss black finish.
Overall, Por-15 has higher ratings than Rustoleum. In the end, understanding the whole above-mentioned debate, you should choose the one you prefer.
Por 15 Vs Rustoleum: Price Comparison
Por 15 would have paid between 40 and 50 dollars per quart. However, even a small can would suffice. Despite what many people believe, it goes much further. If you want, it can even be inverted for preservation. Once it is inverted, you can reuse it.
Anyways, Rustoleum is significantly less expensive than POR 15. For the same amount of quarts, you’ll pay 10 bucks, which seems actually quite reasonable.
Is POR 15 Worth The Money?
The cost of POR-15 is a bit high, but I believe it is definitely worth it in terms of protecting your investment (time & money). In this way, you will only have to paint Por 15 only once, and you won’t have to worry about it rusting ever again.
Can You Paint Over Por 15?
Sure! Por 15 can be painted over because it withstands all types of paints, especially lacquer-based paints. Additionally, Por 15 contains a Tie-Coat Primer for preparing surfaces before applying the Por-15. Therefore, the painting process will be just as easy as with regular paint.
Can You Thin Rustoleum With Mineral Spirits?
If you wish to thin Rustoleum paint, it must be mixed with acetone in a big container or bucket. Mineral spirits or xylene can also be added to paint at a ratio of between 6 and 6.5 grams per gallon.
Por 15 Vs Rustoleum: Which one should you choose? The POR-15 has a higher level of industrial-strength than Rustoleum. You just need to prepare the surface properly. Rust-Oleum has some finicky prep requirements, making it more difficult to work with than POR 15.
In addition to considering your vehicle and materials type, you should choose Por 15 or Rustoleum one.
