I rolled two coats of Lechler 29107 Epoxy primer with smooth Harris foam mini-rollers. Then two coats of Raptor with "Schuller Eh'Klar" Magic Style textured rollers that mentioned Raptor in the description . Both paints are Xylene solvent based and it does attack the rollers, the primer was most aggressive, but only after a few minutes. It could also be that the rollers I used for the Raptor are more resistant, or being more viscous, has less solvent. The unsupported end of the roller, furthest from the handle tended to snap off first, so make sure the roller handle spindle is pushed all the way in. I found the Harris mini roller handle had a slightly longer spindle and supported the roller better too.
I terms of application, I applied two coats of primer about 2 hours apart as the instructions said 1 hour at 20c and it was about 15c when I did it. I didn't sand between coats, assuming this was virtually wet on wet. I then I followed the instructions on the primer
"Wet-on-wet process:
Wait from 1 hour to 24 hours at 20°C and directly overcoat with two-pack polyurethane enamels "
I believe Raptor is a two pack polyurethane paint, maybe not an enamel but probably close enough. So I applied it about 14 hours later, temp was 10c overnight so well under the 24 hours at 20c. Again, no sanding as its wet on wet. I followed this with another coat 2 hours later. I have no intention of making the Kawasaki Mule a concourse vehicle so I think it will be fine, I just want to stop it from rusting in the pick-up bed and the floor in the cab after welding. Its not going to get a hard life, it will be the wife's motorised wheel barrow on our farm. We shall see how it goes
