I won’t venture to claim to know your issues and have the answer but I do have some experience and so I will try to take a stab at this.

We used to use an Earlex 5000. I recall having issues related to orange peel in my finish. I was very inexperienced when we used the Earlex so much of our problem was probably due to ignorance. I do believe the reason your getting the orange peel is due to lack of proper atomization of your material. We use a compressor and gravity feed gun that is made by Woodriver from Woodcraft. With our situation, we can achieve proper atomization through a combination of finding the most effective air pressure and the proper thinning required for our gun. The one thing I recall not liking about the Earlex was that I could not make any adjustment with the air flow. But Earlex offers a few different sizes for your needles you might experiment with and also thinning your material needs to be just right so that your gun/needle can properly atomize the product. You will probably just need to practice and experiment with the things you have control over such as thinning your material, adjusting your gun’s fluid control.

And I am not sure that spraying another coat over your existing coats will correct the orange peel no matter what product you utilize. I believe the orange peel can be improved by doing some sanding and applying a couple more coats.

We use a process that involves spraying lacquer that we do over and over and it works very well for us. I am pretty sure the Earlex can spray either product fairly well, you just might need to practice while making minor adjustments here and there.
