Looking good Hussein. Can't wait to see it painted.....
You & me both
Fun and games today. First time using the gun & mixing the 2K primer. Several problems.
Mixed the primer, 4:1 (I thought) in this marked measuring cup:
Checked the nozzle fan spread, the gun pressure & volume on a test card. Seemed to be going OK, if a little awkward getting the volume up, then the spray seemed a little erratic - like it was choking & releasing.
Got the targa, windshield frame, door jambs & sills, DS quarter shot before that started to get bad
The front fender caps and spoiler got heavy orange peel so I stopped.
you can see the banding along the top of the fender where the spray was uneven flow
Then I found out that the thinners I had bought didn't work to clean the gun - it just coagulated. When I took the gun apart, the inner plastic filter was completely clogged (Primer setting to quickly?). Had to run out & pick up some proper laquer thinners.
I think I mixed the proportions wrong - pretty sure I put 8oz (instead of 6) activator to 24oz primer, so I'm assuming it started getting thicker too quickly in the gun. The primer I poured back out of the reservior hardened in less than 1/2 hr. They said it should have a pot life of several hours.
I lost about 12oz of the primer mix. The other problem, was that in use the gun nozzle pressure gradually dropped from 30psi to 20, with the compressor running pretty much continuously (20 gal tank, 25ft hose). I think I will need to mix & spray smaller quantities to avoid this.
Hopefully tomorrow goes better. assuming the thunder showers hold off. Thunder showers today started about an hour after my fiasco, so I didn't get to try a new batch.
At the very least I can sand it back down.
