#1.Custom Shop Epoxy Primer Grey
If you want the best epoxy primer, we think the Custom Shop Epoxy Primer is a very good deal. This stuff has great corrosion resistance that also has great adhesion with a superior hide.Additionally, we like it how it is very easy to sand, which is always a plus. Also you can topcoat with all current base coats.
We also like that it can be mixed in three different ways. One as a sealer, one as a primer, and another as a high build. In terms of color, it is medium grey, so not quite so dark or so light.Overall, this primer goes on quite nice and has very good coverage. And the general cure time is about 2 hours once you mix it up.
#2.U-POL Raptor Epoxy Primer Kit
We think that the U-POL Raptor is the best epoxy primer for those who want excellent corrosion resistance. This stuff can be directly applied over rust and applied wet on wet.So there is some super advanced resin technology that drastically improves adhesion to bare metals. It also offers pretty good salt spray resistance.
Next, you should know that it does a good job in extending the life of any protective coating applied on top of this primer. So ideally, you can also apply the Raptor protective coating.Finally, we just want to say that this stuff looks great and applies very easily with a brush or roll on. Overall, very impressive looks and very easy to remove with just acetone.
#3.Speedo Kote Epoxy Primer
The Speedo Kote Epoxy Primer is the best epoxy primer for those who want an epoxy primer that can also act as a sealer. This is an easy to mix 4:1 primer that offers a 5 to 10% reduction using a reducer.Overall, we would say that it offers pretty darn good corrosion resistance and has some pretty strong adhesion. It bonds especially well to steel, aluminum, and fiberglass.
We find the color to be quite nice with a gloss holdout. It also sands very easily with a very fast dry time. After 30 minutes, you can apply a topcoat if needed.In general we would say that it lays down very nicely and is just easy to do even as an amateur. Just make sure to have a good reducer on hand.
#4.TotalBoat 2-Part Marine Epoxy Primer
The TotalBoat 2-Part Marine Epoxy Primer is great for boats of course but can also be used on pretty much any surface. It offers pretty insane corrosion protection, which is a must have for marine equipment.This 2 part epoxy primer has pretty awesome improved durability for any additional top coat on top. And a simple 1:1 mix ratio is all you need.
In addition, this is a high build epoxy primer, so it does a great job with filling out surface defects. And of course it dries fast as well as being easy to sand.What separates this primer from the rest is that it comes in 2 parts for two very different purpoes. You have a surfacing primer and a high build primer.
#5.Awlgrip 545 Epoxy Primer
The Awlgrip is a great epoxy primer for those who want something very thick. This is a 2 part primer and it does not come with a hardener.Just keep in mind that this primer is really designed for pros as it is hard to mix and to apply.
In general, we found it to have excellent durability and adhesion and steps above the competition in terms of performance.The only downside is that it really is not suited fro amateurs and you’d have to be a bit of a pro to properly apply it.
