In our shop the deciding factor between Jetglo and Imron AF400/700 is the 'custom color matching'. Sherwin Williams, requires us to get custom colors made across the country, and our Imron dealer can cross reference almost every code, in house, and custom make a formula in the AF400/700 line of paints for us. Both these paints work great with the Sherwin Williams CMO 483705?? primer which is our go to primer for everything.
So if the customer chooses Jet Glo, with a color code, we go with that, if the customer supplies a 'toyota tundra blue' color code, we go with Imron.
Endura is making a comeback though, they sent their paint rep from california up to our shop, and informed us of some new products that they have, along with the fact that they will issue a letter and warranty their paint applied overtop of a competitors primer, which none of the other paint companies will do. Endura also has a couple of new clear coats for helicopter tail booms, and flametracks on turbine engine aircraft, that makes the soot wash off, with water and a rag. They gave us enough to paint our flame tracks on our King Air, to test and try to up sell to customers.
The endura rep from california, said that he actually makes the paint formulas, and thinks we will be happy using their paint for the gloss finish years down the road, as he has adjusted the formulas to make the reds stay glossy longer, and their price point is actually quite competitive.
In closing, you will be happy with either the Imron or the Sherwin Williams Jetglo Paint. They last, they are a hard paint (take a bit of a beating), and they color match fairly well years down the road, because they don't fade that much.
