How do you prevent " The Dreaded Paint Ridge"?

What am I doing wrong? I assume its technique so how can I correct it? I usually end up with a ridge of paint along the edges of whatever I'm spraying and when its time to wet sand I end up with what I'll describe as low valley all along the perimeter about 1/8" or so from the edges and makes flattening the edges difficult. I'm worried I"ll burn thru and edge sooner or later. Thanks

I’ve been spraying past the panel but my edges may be on the sharp side. I do knock them down but only slightly. I’ll try rounding them off a bit more and see if that helps.

Too much paint on edge from doing inner panel/jamb area. Sounds like a big run. Are you hanging the parts as they would be installed on the car?

Everything except the hood was hung as they would install on the car. I have a 4 post lift in a small garage and the area between lift and garage door is where I spray parts and is not big enough to lay hood flat without lift interfering so the hood was hung vertically. Besides the lip of paint along the perimeter of hood I sprayed the clear as well as I ever have. I spray the edges first then spray the field. Is this correct or do you spray hood and then spray edges or does it matter? Was wondering if this could be the cause? thanks NextGen

Ive painted 12 cars in pieces and never experienced this. But I am very particular about sanding primer off all edges before paint.

I assume this is base/clear and your only seeing this effect in your clear? Lighter,wet,thin coats of clear. It kind of sounds like your laying on pretty heavy coats. Universal clear can be layed on heavy without running it but it may be causing this. Not for sure without a good pic of it.

Well I'm actually spraying SPI SS black and then clearing over that but that's a long story how I ended up down that road. But I get it when spraying SS also. Before I sprayed the clear I wet sanded the SS and was very careful around the edge using 1200 wet and then 1500 wet and I got it removed but it takes forever.Then I go to wet sand the clear I get it again. I have had this occur on every piece Ive painted which includes doors ,t -tops, front bumper, rear valance you name it. I'll try and post a picture of it but I usually call on my daughter for these things. I'm old,Technology eludes me. :)

I've had a similar experience when painting the panels on my Riviera recently. Panels were painted off the car and sprayed as they would be hung on the car. I know it's not an edge issue since the door panels have a nice round edge. I spray my edges first and then the panels and go past the end. Definitely more material on the edge just by spraying the edges but I would have though the clear would have flowed out and not left a ridge like it did (only saw this with the clear and not the sealer/ base).

I chalk it up to surface energy pooling up the material on the edge since the clear coat was much heavier than the previous coats

. Knocks down fine when wet sanding.....but just another chore on the list!
