Anyone seen anything like this? Removed crap primer with reducer. Grey scufff pad with scuff stuff. Washed with dawn and water. 700 W&G, waited an hour. Tacked then shot ad pro to see this show up.

If I had to guess I would guess it’s something left behind by the 700. You really need to wipe it dry. I like to let it sit overnight if I can.

Other thing is don’t get aggressive with the tack rag. Tack rags and 700 don’t play well together according to @JimKueneman. Any 700 residue will dissolve the adhesive on the tack rag.

Couple of questions......

1. What is the part you sprayed. I can't tell from the picture.

2. Where are you spray painting. Looks like your spraying next to a garage door?

3. Does the garage door have a opener on it?.....if so, was it professionally installed?

Yes, one door does and yes. Its a jackshaft motor so no over head chain. I havent opened sense putting plastic on the floor and starting painting

I went ahead and applied the epoxy. No sign of fish eyes, indentation or anything. I believe the circles are water spots the 700 didn't remove.
 
Gottcha......

Sounds like you're trouble shooting has some merit.

I inquired about the garage door and opener because 99.9% of the time when an opener is professionally installed, they spray the chain and guide rails with a silicone based lubricant.

Silicone in a painting environment is a big no no.
Even tire dressing can have the same effect your pictures shows.

Seeing as you didn't have that issue after epoxy, it's obviously something else.

Just food for thought, I wait a minimum of one hour after using SPI 710 wax & grease remover, and I wait at least 12 hours after using SPI 700 wax and grease remover.

Since I haven't used Adpro, I have no comment.
 
Here's a Pro tip for you. Wiping down your panels with "Sprayway" glass cleaner before using wax & grease remover catches a lot contaminants ( even water spots) It also saves on expensive wax & grease remover.

I use it all the time, from epoxy to filler to 2k primer.

Also, I clean an area no more than 2'x2' so it can be wiped dried. Trying to clean an area bigger than that causes the wax & grease remover to dry before being wiped dry. As already mentioned, do not allow wax & grease remover to air dry.
 
Okay. Awesome. Good to know.

I try to follow what Chris H says for applying wax and grease remover but i always feel like the 700 doesn't leave the panel as clean looking as solvent base. I definitely need to take better care with drying water during the washing phase.

Thanks again!
