Is this orange peel or dry spray?

[Edward Yemm]

I got this over the second half of the panel. One photo shows a decent finish. This is the first half of each spray. It is a good finish until halfway. Then the other two photos show how crap the second half looks. The first half of the panel is the thin strip beside the windscreen and doors. The second half is the rear quarter panel down to the arch.
I think this will cut out just about but it is a pain having to do it on every panel.
I had this the other day on the boot I sprayed. It was on the roof but nowhere else?
I don’t have any extraction unless I open the back door to my garage but then the temperature may drop too low.
I tried opening the front and back door slightly but then it’s a complete disaster and every single piece of hair or fibre gets blow onto the panel.
I thought it was happening possibly because I was spot spraying any areas I had missed at one point and didn’t have enough paint to do the full panel again. I then checked my work on all spot spraying areas and the first half of the panel that had one area of spot spraying had a nice finish.
I watched a video of someone spraying a home made booth with fans. They did a whole car so there was a lot of overspray being sent on to every un sprayed part of the car. That overspray would surely be collected by the fan.
Their booth looked a lot clearer when they were spraying. My garage is absolutely chocka with overspray until I open the back door then it billows out.
It could be that the front of the car isn’t as badly affected because the spray cloud doesn’t build up and land on freshly sprayed paint as bad causing issues with flow out.
It could also be because I started to run out of paint on the rear of the panel and the gun started to spit?

how much pressure are you spraying with ,,,

 

[Edward Yemm]

It starts off really pleasing to look at. Then half way down it just looks awful. But then, on the rear quarter, whatever you call it? It’s patchy some areas are good. Others too blurry. I’m thinking that maybe I should make a video of my spraying technique and people can tell me what I get right and wrong. It’s frustrating when you can get good results in places but not everywhere. Maybe it’s just over spray from spot spraying around the arch. Maybe it’s where the gun started spitting?
The other day on the other panel, the roof part was terrible like this as well it the rest of the panel was nice. I know I kept spot spraying over one corner of that area trying to cover an area that coverage was awkward on. Maybe it’s just excess paint overspray landing on top of paint I’ve already sprayed and there isn’t enough material for it to flow out and look nice?
I heated the garage right up the other day to 22+ degrees. Today I didn’t bother. It was less than 20. Would have been less still out of the light near the floor of the garage.

Devilbiss SLG 620. Recommended pressure 29. My compressor fluctuates in pressure a bit. It’s between just under 35 and 29 psi at the gun.

 

[Edward Yemm]

Just re checked the pressure. Maybe I knocked the adjustment knob on the regulator at the gun by accident? It’s now between 35.5 at blow off and 31.5 compressor charge. Maybe the 31.5 is just about ideal but then the 35.5 is too high?

 

[tom2207]

it looks like its high ,, and your sure your paint mix is right and nozzle to suit ,, nothings hardening very quickly due to temp , does your gun sound right when its running and the fan is wet ??

 

[tom2207]

what pressure are you reading with the gun trigger pulled , as if you were spraying

 

[Edward Yemm]

Too high? Paint mix is 1K solvent basecoat mixed 1:1 with Medium basecoat thinners. I’m tempted to go up to 120% to see if flow out is any better and the bad areas are then going to resemble the good areas. The basecoat manufacturer says you can do that, but not too much or opacity may be affected.
1.3 nozzle. And yes. If I hold the trigger for 1 second I get a run. I thought that maybe I needed to slow my gun speed down a bit so I tried that yesterday and I got runs everywhere so that’s not the issue at least.

figures are with the trigger pulled.

It sounds like the pressures been too high ,, but the numbers are not crazy ,, Im sure some real painters will be able to help you more ,,, I just paint things , as and when Im not real painter sorry.

 

[Edward Yemm]

I’ll make a video of me spraying something in a minute.

 

[tom2207]

strange how the results vary though ,, thats the odd bit , try dropping the pressure a tad ,,

That’s what I can’t figure out either? Perhaps it’s just my technique in some places. Trying to spot spray one corner at the top of that panel the other day and doing some spot spraying in the second half of this panel today. I’m going to test spray some thinners cans with different settings. See if I get a better result. I really need to get a spare car bonnet or two and spray paint onto those every single time before I’m about to spray my car.

 

[tom2207]

yep , thats the way to go ,,, bonnets should be pence really , but save you lots of grief

Is this just basecoat? No clear used at all

 

[Al Strachan]

As a diy'er myself, setting up for a nice flat single surface is great and achievable. I've done full respray's and i find it very difficult to maintain a consistent coat throughout. Keeping a wet edge while tackling the various panels, nooks and crannies etc is challenging and for the final finish i always put an extra coat for the wet sanding since there will be some areas that need a bit of extra cutting back.

as @tom2207 alludes to, a consistent and professional finish straight from the gun is a tall order from someone who paints cars, compared to a professional auto re finisher with proper training and experience. This is of course just my opinion and comparing against my own experience/skill level.

Base and clear. I did the spot spraying/had the paint start to run out/sputter with the base.

I’ve dumped three coats of clear over this because I knew it was going to happen. I’d really like to have a go in a spray booth one day and see if I’m as rubbish in there. Ha ha.

 

[Edward Yemm]

Starting to have a play around now. Both these are showing good coverage. Nice wide open hand span fan by the looks of it. Both with basecoat/thinner 1/1. I’m not using cheap thinner. These cans are not what I’m using in the base.

This is the photo I should have used instead
