Lumpy finish, too heavy?

Hi all, I sprayed some SPI epoxy today and got into a rush and put it on too heavy in a few areas. I got some major bumpiness (the picture is after 2nd coat). I assume this is caused by me putting it on too heavy? I backed the gun up on the other door and had no issues.

So my question is, is this from being too close? Also is this just cosmetic or will it effect the integrity of the epoxy. thanks a lot

Yes, that is caused by spraying too heavy. Causes could be from being too close, going too slow, air pressure too low, fluid open too far for size tip you are using. It will not hurt the integrity of the epoxy.
 
Texasking, thanks a lot for the response. I will learn from this mistake and try to dial the gun in a little and adjust my technique. I sprayed the roof,quarters and tail panel last weekend with no issues, so guess I got in a hurry. Thanks again
 
Tex is a 100% correct, if your going to make a mistake, you made a perfect one.
If 2 K primer is next spray the next day and don't sand the epoxy.
If base is next slick out with anything from 1000 wet to 1500 wet and shoot base.
 
Thanks Barry, that’s good to hear. My plan has been to strip down and epoxy a few panels at a time until I get everything covered. Then, I was going to scuff, then shoot a third coat of epoxy on individual panels a few days before I skim the panel with body filler,block, then high build. Considering the limited time I have to work on the car, that seemed like the most robust way to get the best adhesion with the products.

I haven’t done much painting in awhile, so if there is a flaw in my plan or if it’s overkill, someone please let me know. Obviously working one/two panels at a time is going to take me a while, but it may be the best I can do. Thanks again for the response
 
Also, make sure you’re mixing it exactly right and aren’t misreading your mixing cup. Too much activator might cause the same effect.
