I’ve been spraying for a little under a year now, I just graduated high school, and I still have problems with laying down the paint sometimes especially metallics, it comes out “blochy” , I use my Tekna Prolite for base, I’m spraying PPG ShopLine, and recently started using the ShopLine Plus thinking it would help, I know it’s bottom line paint but nobody wants to pay the money for a higher line I.e DBC. I’ve tried everything from spraying at the recommended psi, and even going lower psi but still doesn’t come out right. I know there is a lot of variables that could affect the paint, but any help, tips , or suggestions please. I’ve been getting to the point where I want to buy a different gun like an Iwata base coat gun. :hunt :huh:
July 4, 2012 at 6:55 am #37572sometimes it helps on the cheaper stuff to cut your base 50/50 on the final coat with some colorblender/clear base. Had to do that with dbc alot on their metallics, so I’m sure the lower lines are worse

I will try to get some blender or clear base and try that, if not just keep trying different techniques until I get it I guess, I have a truck to paint in the next couple days so I’ll see what happens. :unsure:
July 4, 2012 at 7:21 am #37574Try a slower speed reducer to see if it helps, increasing your distance and drop the air pressure a couple of psi for your last coat might help too.
These guys gave some good advice. Don’t bother wasting your money on a new gun. That is just the nature of the product. I’ve used that base before, and the metallics are near impossible to lay out perfectly. Take their advice and work on your technique to get better, but don’t expect miracles.
And if you wind up painting some smaller jobs, the price difference between shop line and a better product isn’t that great. Plus, most better products cover/hide much better so you will likely use less material with the more expensive paint.
July 4, 2012 at 11:27 pm #37576you could also do a few other things. one put a coat of sealer down first, like jay said slower reducer, play with the fan spray wide open isn’t always good. put dbc500 down first then color. make sure your overlaping well enough.

I’ll try all these things, although I have been using slow reducer, I’m going to try and narrow my pattern down some more and drop the pressure, and maybe get some blender as well. I hope to get it down soon, I hate seeing that on my finished work, as I take pride in my work
July 5, 2012 at 7:41 am #37583I wouldn’t touch the fan settings or fluid settings,increasing your distance on the last coat should fix it for you.Try a higher quality slow reducer,you would be surprised how well that will work.Your tekna prolite is an excellent base gun,no need to change

I was having the exact same problem with Nason untill I tried Jayson’s advice, what I id was double the distance from the surface and that improved like 95%. Good luck
July 6, 2012 at 4:21 am #37594[quote=”smooth” post=26794]You could also try a drop/orientation coat after you achieve hiding.This means lower your pressure and increase your distance to 10-12 inches and mist the metallics on 50-60% overlap so they look even.[/quote]
You need to be careful doing that with solvent base,depending on the brand it can cause adhesion issues and is not reccomended.That is why I suggested droping psi a couple pounds and increasing distance and still put it on in a medium wet coat,kind of a cheaters drop coat but still wet enough not to be.July 6, 2012 at 6:05 am #37596[quote=”Jayson M” post=26782]Try a slower speed reducer to see if it helps, increasing your distance and drop the air pressure a couple of psi for your last coat might help too.[/quote]
I agree, a larger tip size can also help.
July 7, 2012 at 8:42 am #37604Well I sprayed another silver today, it came out better, increased my distance a bit, lowered the pressure to about 15psi, and did the mist coat at the end, it came out better but a tiny bit blotchy , you could barely see it. It came out really good tho. But then later the day I sprayed a bed, same paint, same technique and it came out more blotchy, so Im not sure what’s going on, maybe the temperature is affecting it. :stoned
July 7, 2012 at 8:15 pm #37605You dropped your pressure too much and went to slow,your distance should have been about 8-10 inches,vs 4-6 inches for coverage coats.If you normaly spray your solvent base with the tekna at 25 I would have dropped it to 22psi on the last coat.WHAt is the temp you are spraying at?
