Both of these products are 2K or 2 component. The aerosol picture you provided should be a Kwasny or "Spray Max" product as they are in fact producing a true 2K aerosol. Their epoxy is good for about 5 days once activated. The Urethane primers that they have are either the rapid or regular and they have a much shorter "pot life" of a day or two at the most. All of the Spray Max products are body shop quality and would rival any major paint brand's 2K epoxy or urethane high build. They are just really pricey. The added benefit of using their products is the spray can sprays just like a primer gun!!!
First put on the epoxy primer, then body filler. Sand and recoat filler as required. The high build urethane can be used to cover the filler, the bare steel surrounding the body filler and the epoxy. The bare steel around the filler is a result of sanding the filler and it is okay to high build prime this area without epoxy primer. |
I got the Spray Max 2k epoxy primer in a can... I plan to spray it on my bare metal area's on the some doors I did some shaving on. I thought the test video said good for 5 hours once activated. When I get home i'll check the label info. Either way though, I hope to have everything sanded and ready by the 70 degree weather coming on Thursday and Friday to spray this primer...good to know I should have more than 5 hours to use this stuff once activated. The pic was for an example. Its off of the Eastwood site. I posted it because there might be someone else that reads this and might need to buy a can or 2 to do small areas like I am. $22 a can is cheap and easy if you just have a small area to spray. Thanks again, Foot Stomper!
