I had the gun sat around with basecoat in it for hours before I did that test spray. I’ll clean all the dry paint off and re try it. Maybe one of the air passages was blocked until I washed thinners through it? There was that patch of dried up paint inside the air cap on the photos. I’m clueless as to whether this patch, even though not blocking the circular air passages, would affect the airflow slightly at the bottom of the fan? I washed thinners through the gun before spraying the panel though.
Ok. Thanks. Will follow this. I will take off air cap after every use and brush it off. It may have been a bit of paint clogged in there from when I last used it. I washed it through but there was perhaps a bit of paint partly blocking something?Leaving the gun sitting still for any length of time will allow the metal flakes to settle to the bottom of the pot, which will cause blockages, sputtering and a coarse finish in places. Put some paint in a pot and watch it settle, surprisingly quickly.
Keep it moving or clear it out before putting down and stir it. Don't put more paint in the gun than you need in one go, pour the excess out into a separate pot and put thinners through the gun before putting it down. Stir the paint before putting it back in the gun. You can work out the methods that suit your way of working.
Thanks. As said. I would have Flatted those areas that are showing edge marking with a block. I didn’t. I lightly scuffed over the edges without one because I kept constantly cutting through to the barcoat etc under the primer. This was after 4-5 coats of what was supposed to be cellulose filler primer. Clearly it wasn’t. It may have gone bad after years of sitting around. The new primer I have is a lot more thicker flowing out of the can. Coverage is excellent. I did get one thing right during my prep......It's your prep that is letting you down I'm afraid. A clean gun is essential for a half decent result.
For panel prep, you need to flatten that back and then 3 to 4 coats of primer, high build will do. Then flatten off with 1k grit to make it perfect smooth before 3 coats of base coat to give coverage as it's thin, 15 to 20 mins apart. Then 3 coats of clear aftet 15 to 20 mins and 15 to 20 mins apart.Let that dry for at least a week before flattening with 2k grit paper and then polish.
Have to see how it fares up then. I’m going to buy some epoxy primer soon. Should hopefully be no reactions on the rest of the panels using that stuff. Don’t know what to do with the P88 cellulose that I’ll have left over. Was going to use it to paint my trailer but not sure if it will be any good for bare metal as I don’t think cellulose is an etch primer?wait till it cracks in the sun because you used barcoat
wait till it cracks in the sun because you used barcoat
I remember mentioning in another post about barcoat being rubbish and too many coats of paint causing cracking.
That’s what I want to do. So, let me check this.sort yourself out with some proper breathing gear and you'll wonder why you didn't make the transition sooner. Once you get the hang of it, 2k is so much better and i cant remember the last time i had a paint reaction.
