Epoxy primer scratch before high build

[Tony1968]

I hit this with 80 grit. Is this enough to hold the high build primer?
Been in epoxy for months so it's cured obviously.
Clean up and spray or ?

No specific sandpaper recommended and I've searched. I've read between 80 and 220 to scotch Brite. Nothing definitive
Thanks

80 grit is more than sufficient, I normally use 180 or 220. Hell a red scotch brite is enough!

Laid down ok. I guess. A little peal but I think it's my fault because I'm doing it lefty and have bad coordination. 3 coats. Block sanding soon

Looks good! Now, hit it with some contrasting paint or guide coat to help in your block sanding to ensure you get surfaces flat as can be. I like to start with 220-grit and end up at 600 before sealer. I like using this pad for block sanding since it fits comfortable in your hand and uses hook-it disc sandpaper.

As always, take your time!

When block sanding, it’s best to use a proper block. That one is not it. I only use that for taking texture out on new parts. I used to use dura blocks, but recently got into using acrylic. The hard acrylic cuts way flatter.

I've got a durablock kit but also read about using a paint stick for sanding Can't afford acrylic blocks.
But I can be creative with some harder foam or whatever

You can easily make your own acrylic blocks. You just need to cut a piece to the size needed.
