Pinhole questions.

[Tony1968]

Blocking in 320. Using dry guide coat. My eyes are not what they used to be. So I got up really close with an led light and noticed these. Are they pinholes? I'm assuming yes but haven't seen them yet.
How do you guys clean out the hole for a 2 part finishing glaze? And using a razor blade is what I see guys using for glaze but can I use something like an old ID card or credit card? They really are as small as pin 📌 points.
Thanks guys.

Looks to me that you need one of two things - sand further or more 2K.

What procedure did you use prior to priming? Pin holes are normally caused by air pockets in body filler from the mixing process. Normally pin holes are fulfilled before priming takes place with a two-part polyester. When pinholes appear in primer like you have you can fill them with a product called combee putty. Then sand it and paint right over it if your using a sealer.

those are fish eyes caused by contamination usually of the petroleum persuasion of some kind.some of that will block out they're not to bad.whatever doesn't block out with the 320 skim with the razor/spreader in a squeegee type fashion with whatever two part putty you've been using then finish it off when you finish sand with the 400.pass on the combee putty as it's 1k and there's more chance of it shrinking vs the two part you've been using thus far.looking good mr

Are you saying don't re-spray it? Or fix what's there with putty?

Yes fisheyes! I don't know if you remember but I had the fisheye issue when I first laid down epoxy over metal. I had a problem and they surfaced.
To clean out the dry guide coat in them before I glaze over them what would you suggest I use? I'm thinking I can twist a small drill bit slightly

BTW when I first saw them I coated areas again and blocked again. They went no where.

it's pure preference.if this is the only issue with the panel when he's finished sanding and there's not a lot then repriming vs skiming is up to him what he's looking to do.if he broke through in a bunch of spots then mix up the primer.the repriming might be more than he's up for.there's no wrong way they yield the same outcome.
