Inches from painting need advice (pic)

I'm finally about to spray the rear quarter on my practice car.
I you look at the pic I feather edged the blue at the top of the panel. Should I spray the 2k primer surfacer right over the blue? I'm assuming it will come off when I block sand...

yes you want to bridge the gap between the two different levels of surface. spraying over the existing feathered edge, then block sanding will level it all out.

Thank you, I thought so but thought I better double check. I've only done a little painting on completely bare surfaces so this is new for me.

Looks like bare metal, I'd put down epoxy first

There is a patch panel I welded in, further back toward the tail light, it has some filler back there, I removed paint up to where it is in the pic because there were scratches thru the color. My plan is to 2k high build, block sand, primer sealer, color and clear. I didn't know much about epoxy when I started this, my next vehicle ill epoxy first.

You really only needed to remove the paint a couple of inches past the repair area and then fether edge it with 180. Beyond that I use a scotch brite just to give the primer something to bit into.

Typically you should put epoxy or self etch primer over bare metal before you put filler primer on.

it had some pretty long deep scratches down the length of the panel, but you are right I did remove more than I needed.

I know everyone has there way, and not to open a can of worms but I just followed evercoats directions, apply to bare metal prepped with 180 grit.

I guess ill find out if it works or not

you all got me thinking a little bit. Since my filler stage is done, I was going to shoot 2k high build then sealer. should I seal it first then shoot the 2k?

Apparently the Evercoat is a DTM primer, so I'd spray it and then the
sealer. Typically the sealer is the last primer coat before spraying color.

Its hard to understand what people have going on from a picture.

I like to keep the repairs areas as small as possible as it just makes it easier to blend colors. With a metallic color it never matches quite right. Sometimes you can get lucky but if it is a older vechile its hard to get it right with out blending into the next panal.

If it is a DTM primer I would only seal it if you have metal or body filler showing.

Thanks for the replies, this is my practice car so I'm trying to learn as much as I can as I go. The car is in pretty good shape but has a handful of small dings and scratches so ill get a good base expierence. Its a 1500 dollar commuter car so if things don't match up my first time I won't lose any sleep over it.

Good call on using a "practice car" first. Looks like you have an NA Miata. I plan to do the same process on the same "practice car" (although red) before I spray my '41.

Good luck and let us see the results.

I have now sprayed my acid etch primer and my 2k urethane primer down. Acid etch came out perfectly but the first 2 coats of 2k came out dry, I think it was too hot in my garage it was 87. So after sanding I sprayed again with a slow reducer and it came out much better. Well im to the point where I need to sand again with 400 then apply my sealer.

How does a guy know when to stop sanding the "bridge" from the old blue and the primer that I laid down? Hopefully you understand my question but since I need to sand down the primer that is over the blue, how can i tell where the blue stops since its under primer right now??

use a guidecoat. i use cheap black spraypaint and dust a light coat over the primer. then hand sand with a long sanding board in a crosshatch pattern until the black disappears evenly. if you hit shiny metal you have a high spot. if you have black in spots that will not sand you have a low spot.when when you can sand to primer evenly its perfect.
