it does yes. I use it for such purposes most of the times. Even on topcoat whenever I only have a gloss or semis left. So long as they are of the same type, which is acrylic.

It’s dish soap

Nope

I had the same thing happen with my primer, first off shake the bottle. Then for every 20 drops you also want to add 5 drops of valejo thinner and one drop of airflow improver. 4/1 ratio paint to thinner seems to work best for me. I'm using an HC eclipse.

@@blaaaaaaaaaaaaargh I know this comment is 2 years old but I just used vallejo primer for the first time today. The ebay seller recommended just using vallejo flow improver, that worked fine with they grey but the black was constantly clogging, I'll try thinning the black next time, thanks.

This thread reflects one basic problem…Everyone has their own method and their own recipe for success. And no end to the places one can visit online to get every variation thereof. Oddly enough, my go-to primer used to be Rust-Oleum gray 2X Coverage rattle can primer. I’ve had great results with it in the past unless I got distracted and trained it in one spot just a little too long, but that can happen with any primer. I bought the 200ml size bottle so I HAVE to figure out how to get it to work! Last night I started with a freshly stripped and cleaned a/b, and a ratio of 3 drops thinner to every 10 of primer, with 2 or 3 drops of flow improver. Mixed it up in the cup and set my compressor to 15psi and from the very first pull on the trigger it was gummed up. So I’m going to kick the psi up to 20, increase the thinner and try it again. If I can’t get it to function properly, I’ve got some of the Vallejo black primer I can try in its place. I’m running out of hairs to yank out with this primer bullshit!😄

Kshatriya 8271 Vallejo recommends a PSI of 15-20

Sanding primer? It's not necessary cause it's designed this way (it's not a automotive primer). Just avoid thick layers of paint and let it dry completely before painting with base colours.

Jackson Golden yes, that should be possible.

Old, bald fat man Did you bother to clean your model before you tried painting it?

Zelu Tom no, I wouldn't recommend this as a filler. What you use for that would depend on the material you're priming.

Thank you for your reply! What would you recommend to fill in the gaps/voids after sanding to make it smooth? (I'm working with 6" action figure)

Zelu Tom for plastic items, I use Perfect Plastic Putty by Deluxe Materials but there's also the Mr Hobby range of "surfacers" which might be more suitable for small imperfections.

thank you very much!
