smoke causing fisheyes?8/23
My shop is in Washington State and we are socked-in right now with smoke from wildfires so thick that visibility is under a mile. We are experiencing a fish-eye problem. I suspect it's from the smoke. It's worse in the mornings when the smoke is mixed with moist air. Kind of an odd question, but does anyone else have any experience with this? I'm just wondering if this seems plausible or the most likely scenario, because if it is I won't go hunting for other causes, we'll just wait it out I guess.
I don't have an answer for you but...l live on the boarder between Ca.& Or and we have been hammered by the smoke for a month now (even reaching into the hazardous air quality zone a 1/2 dozen times) and l have had no problems. In that time l have sprayed clear 2k poly, clear & pigmented CV and clear and pigmented wb.
Open faced booth or enclosed? We're in WA and have 2 sets of tacky filters on incoming air. It's smoky here too, but we haven't had an increase in airborne debris in the finish. It's all over our cars though.
It depends on the nature of the smoke particles. If they are oily, it's easy to get fisheyes. Even if they are not, I could imagine a particle landing on the surface just before the coating does and making a center for a fisheye. It also depends on the coating. One coating might wet out a given smoke particle, while another might not.
I would agree that it could be completely location specific with regards to the smoke. Type of trees/woodland, whether houses, trash, vehicles, are involved in the fire. There is no telling what is in the smoke from one area to the next.
Yeah there are definitely things that cause fisheyes when they burn.
We had a HUGE problem a few years ago with any diesel delivery vehicle. If they arrived and idled for any amount of time, spray booth would get crazy fish eyes.
Some of our portable heaters can run on diesel, and we tried it when the local places ran out of kerosene, and of course, it fisheyed everything in the spray booth.
