bits in paint (2k primer)

[carl0s]

Hi.
Initial trial run of painting after spending months setting up driers/condensers, getting breathe-cool air fed mask, etc.

So although I have a bumper to paint, I am trial-running on the simple diffuser part of the bumper.

Using kapci 2k primer, with some 803 flex additive.

I did one coat, seemed OK, although I realised that I was clueless about the paint gun controls, and the "mini on-gun regulator" that I bought was a total failure (cheater valve I think they call them.. anyway the gauge was useless and showed either 0 or supply pressure, but didn't show the valve's output pressure), so pressure was a total guess.

So I left the coat for 5 - 10 minutes, then came back and set the desired pressure on the wall instead on attempting to use the mini gun regulator, and did another coat. And then I got chunks in the primer!!

So my question is... :

Is this because I didn't use a filter when filling my paint-gun cup
or
Is it because I left the paint for 10 minutes and some of it set inside the gun?

I did not re-fill the cup or anything. It already had plenty in it.

Now that I think about it, I should have emptied the gun shouldn't I ?

Picture attached.

Yes.

But I don't bother filtering the primer as I'm going to block it out anyway.

either put a filter on the end of the suction pipe in the gun or nick wifeys tights and place over the pot and tip the paint in and filter it u dont want any bitty paint blocking the gun up

I thought I'd've seen any lumps in the paint when I was mixing it with thinners/hardener/flex in the mixing cup?

I have ordered some paper filters now.

You should always strain paint and Primers ...These bits in the primer are closed parts of primer...these are not potentially mixed with activator as its hard on outside but still un activated inside

If you strain you will never get this

You also don't need flex additive for these parts

Always filter my paint thro old TIGHTS, Recommended above::: cheap and plentyful, generally filter thro a double layer of them.
or nick wifeys tights and place over the pot and tip the paint in and filter it
