I don’t have a 4″ tip.
I posted a video on tips on my site.
I don’t like spraying at a 12″ height.
I use a 6″ tip…and lower the gun.
Also…if the line I’m Re-striping is 4.75″ wide…I can still cover it with my 6″ tip. I just raise the gun to about 6″ – 7″ inches off the ground.
Next…I use all .019.
Anyhow…I hope this helps.
Let me know.
Dan
