Reaper Brush-on Primer - Can't measure drops because it oozes?

Recommended Posts

Hello all,


I bought an Additives Triad the a little while back - I think it was late March - and I was surprised at the consistency of the Brush-on Primer that came in it. I used it right away, and it didn't form drops out of the bottle, but rather it oozed out of the dropper, acting more solid than liquid - it reminded me of squeezing toothpaste from a tube, with it coming out of the bottle in a snake-like fashion rather than drops.


Is this normal with the Brush-on Primer? It's just been difficult to measure water ratios with the primer acting like this, and with this being the first time I've used Reaper's Brush-on Primer, I'm not sure if the results I've had are typical for this product. It seems to cover metal ok, but on plastics - specifically the plastic used by Privateer Press - it doesn't cling to the miniature, rather it seems to bead like water on glass. (I'll be re-cleaning the pieces to ensure it's not some sort of release issue, but the PP minis seem to have a smooth, gloss-like finish on them that seems to repel the brush-on primer from sticking. I've had the same issue in the past with brush-on paints on my Gundam scale-models, if they're not spray primed first.)


Any advice would be helpful - I like being able to prime by brush. I don't always have the time to spray paint - I usually get the bug to paint at odd hours.


Thanks in advance!


My 2 yen,

If you bought your brush-on primer from Reaper, the toothpaste effect is surprising. That's something that happens to dropper bottle paints that have been stored for a while. A fresh bottle should behave like a thick liquid. I've seen the "snakes" with many different bottles that I've had around for years and years. I've found if I add water/etc. to it, usually it works like it should. You can also squeeze it out to get down to the thinner paint if it's gotten too bad to use.


I've never used it with plastics, so no help there.

If you bought your primer from Reaper you might talk to them about it. However, opening up the squeeze bottle and adding a bit of water should take care of the problem for you. Some of my MSP that I've had for a few years thicken up a little. I just add some water and they seem to be good to go again.

It should be about the same as the paints. You should not have to thin it.


Have you shaken it really well? Cleaned the nozzle with a pin?


If it is still coming out thick, carefully pull the nipple top off and go clean it. Use a toothpick to check the consistency of the remaining product. If what is in the bottle is thick, then call Reaper to return it for a new one.

I'll dropper some water into the bottle - I've been thinning it on my palette anyhow. I actually did send a message here, but I hadn't heard back.


It's not a huge deal - it's more of a case of not wanting to call something out that's acting like it should. This is primer, so I wasn't sure if it was supposed to be a bit thicker.


Thanks for the replies, everyone!

      This was from a couple months ago; I was pretty unsure what I wanted to do with it. Overall, I'm pretty happy with the way it turned out, particularly given that I think I only had three different colors of blue paint in bottles, and two of them were pretty similar.

      Watch out this time of year for this fellow, he'll come riding in with the blizzards!

      Catching a bit of a 1970's version of A Christmas Carol while channel hopping today reminded me that I still had these gals to paint:-

      I was planning on extending Presents base with putty but mine had dried up (Plus I'm not sure I would've had much success reproducing that wooden plank look anyways), so she's going to look a little weird (Although she already looks a little weird in her pirate cosplay).
      Just waiting on them to dry, and then, hopefully, I can start painting them tomorrow.
      Won't get them finished by Christmas, I'll probably still be working on them well into January, but I should be able to finish them eventually.

      and the last of this month's work, pretty sure can't see another one out of me with only half a day left. I know said was gonna take a break for the holidays but got bored. I gave up my blue for that stupid hellborn skag Skarre, now what color do I choose. While looking at pirate pics for ideas I noticed alot of them were deplicted as wearing brown alot but could recall seeing any or hardly any pirate mini's painted as such, so....

      Last of this month's work. I know said was gonna take a break for the holidays but got bored. While scrounging around my loose mini's I came across her, don't know what happened to the wraiths but decieded to paint her alone....hehe no choice without the wraiths. She always reminded me of someone and wanted no needed to due her as such as i could, so without further ado....
      ....A.K.A. "the Scarlet Witch"
      I wanted her to be at least more sinster looking thinking about going back and giving her a purple eye shadow maybe that will help with the over all look of the face.

      Last of this month's work. I know said was gonna take a break for the holidays but got bored. When i first got her i noticed she was so danity, so skinny it felt like I was painting a 25mm.
      What I planned to be an easy paint job turned into any but.
