Water based primer thinners

[VW]

I have 1l of Mipa water based primer filler. I don't have the mipa thinners though.
I use water based paints in my airbrush and the thinners is basically water and alcohol (can often use screen wash!).

Think that will work?
I have decent cellulose thinners too.

I've not used water based primer before. Had a look online but can't find the right thinners, or any details on what kind of thinners it is.

Any painters know what I can use with this? It's basically being used to fill pits left after rust removal. Will be top coated with coach enamel.

I've often used distilled water when I havent had any proper water based thinner and never had any issues.

Mixed a little with some screen wash and sprayed a couple of test pieces.
Seems to work just fine, I'll see how it sets up.
Never used water based before. I over thinned it a little. Also can't lay it on like you would solvent based (2 coats in quick succession seems to have created some runs).
Also seems heat will be my friend with this as it's obviously going to take a while to dry.

But, other than that, it's nice not having the fumes! It also seems to do the high build part of its job well. Clean up is super easy too.

So, less thinning, warm parts, no wet on wet coats and all should be good.

If it's the Mipa Grundierfiller (Think I've spelt that right), 1k Waterbased stuff you can use it straight out of the tin without thinning.

If you think it from memory it's 0-5%, so only a tiny bit of thinners, I wouldn't use screenwash, I'd just use distilled water you can buy from Asda, or boil water and let it cool as an alternative.

Waterbased needs air movement as well as heat, so put a coat on and then use a hair dryer on low or medium heat to flash it off. It drys much quicker with air movement than just heat on its own.

Yeah, that's the one.
Only tried screencast as it's what folk use with water based paints when airbrushing models. The little bit of alcohol in it helps it flow.
I have distilled water too though.

Yeah, I thinned it way more than that! Keep thinking it's celly 😂
I'll fire up the log burner, get the fan out the loft and keep the hot air gun to hand. I have lots of small parts to paint!

I'll try it neat too but it did seem a little thick, but again, I'm comparing it to cellulose!
