How can I stop edge marking? I am using a fill primer over prepared old paint ( On the repaired spots only ) and after 22 hours of dry time. After sanding with 600 wet then cleaning, I spray the Base coat and the edging occurs around the primer….HELP!! Should I use a different primer or sealer over the fill primer? As long as a whole panel is completely primed I dont have an issue,the Base covers nicely, only on the repaired spots does this seem to happen.. Thanks.
Going on the few details you’ve given, it sounds like the base could be lifting the edge of the fill primer. How are you preparing the panel before priming? Particularly around the repair where the edge of your spot primer will be? I like to use a 240 or 320 DA disc as a minimum, to give the primer something to bite into.
What type of paint/primer are you using?
I had this happen once quite a long time ago when I had a bit less experience than I do now, but I am by no means an expert and someone else will no doubt give you some good advice.
Could be a couple of things, make sure your using a good qualitly primer not cheap spanish stuff like I did. You may be overwetting your basecoat and also try priming a slightly bigger area and start to sand the primer in between the repair and the primer edge to feather the primer out, don’t feather it in from the edge to the repair. Hope that makes sense??
Spray the basecoat in a really really REALLY thin layer over the spot (over the spot only, not the whole panel) and blowdry the layer immediately to get the thinner out asap. Repeat till fully covered. This prevents edge marking. In the end you can do the whole panel.
make sure your primer is going over a well sanded surface 400 grit at least an your problem should be solved
most of the edge marking ive ever seen was from lack of tooth for the primer hope this helpsCould be you are not sanding your primer thoroughly enough, I had this happen a couple times with Evercoat uro-fill primer.
If i think i know what your talking about…I have seen this happen when using hi-build primer and hard lineing your masking area. Make sure you dont stop your primer in the same spot every time you end up with to much film build and it will actually create a high spot in your panel. Once you get done blocking out your primer take a clean towel and wipe your area to check and make sure that its flat. Alot of times you will feel stuff that way that you didnt with your bare hands.

Ok, I think I just was not sanding back far enough in the old paint.This problem seems to be fixed now. Is it me or does the coverage suck on Base Coat paint It seems way to thin….I miss Immron! Thanks for the help People!!!
featheredging could have been the problem , but a tinted wet on wet sealer might help

Some products cover well (especially with some of the waterborne products). What base are you using?
