Another Orange Peel Thread :(

P

PUNISHER VETTE

Sorry all. I didn't want to hijack the thread about orange peel for the other guy so here's mine.

Using my 400 with a 1.4 tip spraying primer just so I can get used to it so I'm less likely to screw up the base.

I sprayed 1 medium coat(which I hear you should do with metallics(although this is primmer I wanted to try a medium coat anyway)).
Then to use up whatever I had left in the gun I made a 2nd pass on half the hood before I ran out.

That 2nd pass had terrible orange peel at first. Less once it dried a little.
Should I just stick with thinner coats to avoid the orange peel? I'm terrified since I'm doing a metallic if I get orange peel I'm screwed...
I also read the orange peel thread that says it's fluid adjustment... but should I lay it on even thicker? seems like the thin stuff went down smoother.



The one coat side



The orange peel on the two coat side....sorry...hard to take a pic of it.
 
It's Epoxy.

Almost all the orange peel has flowed out of the two pass side except for one or two spots where I'm guessing it was slightly heavier.

Sorry. The pictures really don't show what I'm worried about.
I'm just trying to get as good as I can with the 400 so I have less of a chance screwing up when I go to shoot the base.
 
Just going on to heavy, one med wet coat and then let it flash before more. If you double coat the epoxy it starts to do strange things
 
Are you doing a basecoat/clearcoat job? Also can you post a real time video of a couple passes?
 
Medium wet with the epoxy, ample flash time between coats. I don't worry about minor orange peel at the "priming" step but I do like to reduce 5-10% at the sealer step to get it to flow out.

Heavy epoxy will tend to crater and peel more than lighter epoxy. I tend to spray it more like base coat. Just heavy enough for coverage and then a second coat for security and then a third just because.
 
Also if you have an old hood or fender etc. They make good practice with your technique and gun adjustments. I know it seems like a waste of materials but it easier to rework something that doesn't matter as opposed to something that does.
 
That is the old hood I won't be using on the car. I just want to treat it like I'm shooting base metallic to simulate how well I can do. So seeing any orange peel or bad stuff makes me feel sad :(.

Like I had a little dust flying around... so I know i need to work on cleaning and blowing off the car before I spray. I wiped it down with W/G remover...but that only got the hood. What it didn't get was the dust hiding in the hood grove that must have had dust in there from when I sanded the hood a little before hand.

Once it's primed it'll be the first thing I paint with the metallic PPG expensive stuff to see how well I can paint metallic, then clear, then cut/buff....before I attempt it on the car(engine bay 2nd).

I know of no other way to get practice other than painting this hood...with the real stuff :(
Expensive but... how else can i get real life practice?
 
Here is the video at regular speed.
Looks like I need to work on my overlap better. 50%? or 75% for metallics?

According to the videos I watch from Eastwood with Kevin Tetz(good youtube videos that seems to be helpful to teach me)
He goes MUCH faster and closer. I just think for a beginner the slower I can go the less likely I'll screw up my technique. But maybe I should try faster/closer to the panel?

Kevin basically says wide open fan, adjust volume/distance to suit your style?

Okay, you seem to be laying it in a bit heavy. Try going a bit faster with just a little more over lap 50%. I will say this, the way I shoot metallic base is completely different from how I lay down primer so practice with the real deal is very important. Usually your jobber will have a mismatched paint table and you can get a quart for like $30. I shoot metallic with heavy over lap and fast passes, first coat heavy and then next 2-3 light to even out metalic. I dont focus on perfect overlap but how the metalic is laying out.

I guess I can't have it both ways. I can't have a TON of practice without painting the hood and having to sand it all back to do it again for more practice. It would be nice to paint the hood in the color and paint I plan to...but that's a very expensive paint job I'll just be sanding back away.

Not that there's only one way to paint but Kevin Tetz style was thin coats to get coverage then a "drop" coat wet on wet for the last or 2nd to last coat(can't remember which)....which looked a little sketchy for me to attempt.
 
best practice for learning to spray metallic will be a silver, gold, or pewter color. lay down your 3 coats and then bring it outside in the sun and look at the metallic from multiple angles. If you can spray a high metallic like silver with no modeling or striping you can spray any color

The bigger thing I noticed was you hit the flat and then hit the edges after. do most of you paint that way or do the edges first so your final passes on the flat are more consistent than having some dry spray from the edge ending up on the top, especially when you spray that metallic.
 
I don't know what the right way to do it is. I didn't notice much dry spray though. I think because most of the hood was painted pretty quickly and was still wet enough that any overspray blended in?

I wasnt implying you did it wrong, just asking what these experienced guys usually do.
