It has no self levelling properties at all, but it is: easily applied, easily sanded, and is by far the easiest product to clean off spray equipment that Ive ever painted with.

This is not a high build primer at all, even out of the can it is already too thin to spray. It needed several coats, to build up a sandable surface. I stirred up all the solids in the can. Otherwise I think it would be a good product.

Great products from Stewart Systems. Goes on smooth and covers and sands well. Best of all, no smell or harmful chemicals. This is not latex. Its only transferred with water. Love it.

Stewart Systems Primer Sealer White Quart

Easy to use, didnt totally stink up the booth, covered scratches beautifully straight out of the can, and made for an excellent finished product!

This stuff cant be beat. I can prime and paint in my attached garage with no worries about fumes or harmful chemicals going into the house. The other stuff is covered wagon technology.

Needed to fill the weave in 1.3 oz fiberglass cloth that was applied over birch plywood fuselage. Two coats did the job nicely without the need of heavy “filler” primers and then mucho sanding and contouring . I lightly sanded with 220 dry before painting, but believe I could have just painted over a smooth application of this primer/sealer. JJ Sinclair

Goes on easy, sands easy........doesn’t clog sandpaper........GOOD STUFF !

I used Stewarts system before on another airplane, it is water based so not toxic and or cancer causing . It works good, easier to use and not requiring a breathing device just a mask. I have not shoot this color of paint but we shall see. Again like with the cylinders I bought a few weeks ago in 10 years I will be able to tell you how good this material is, well see how long it lasts.

I am using this on my Velocity. Its done a great job so far.

Stewart primer and paint is working out great on our AT-6 tail section,its holding its Shiny finish...we will use the Stewart process again on our Stearman..

I have used this primer for about 4 years and had good results, even when the primer was well past the claimed shelf life.

I love the Stewart system. We have covered 2 wings and the products are great.

This primer may not be quite as tough as epoxy primer, but its other properties more than make up for it. It's easy to spray with no need for extensive protective gear and no solvent fumes. Whatever you don't spray can be poured back into the can - try that with Akzo. My only very minor gripe is that it's fairly easy to knock off of sharper corners, but I think it's a problem with any primer.

One of the better water based primers Ive come across. Works very well in combination with the de-greaser and etching products. Easy to prepare and apply with a spray gun. Forms a good bond with the metal surface and good corrosion protection.

As an experiment I tried using a foam roller and than a brush to apply this primer.. according to the on can instructions you shouldnt have to thin it. without thinning it did not flow and the foam roller caused a lot of bubbles that left a texture when dried that took a lot of sanding to get out. After adding distilled water and using a good brush i got better results. However spraying is by far the preferred method. It produces a nice hard but easily sand-able surface

It did not adhere to steel as well as expected.
