"How To Spray" Ultimate Modelling Products Primer 

Thanks Paul. I've been using your primer for months but learnt a lot here. I also watched it twice and have no questions at this time ;)

I learn so much valuable info from watching your videos. Defiantly my go to RU-vid channel.

Paul, yet another excellent tutorial. I ONLY use ump primer and i love the stuff. Excellent finish every time. Never had any issues with it or any of your products for that matter. I even mix the primers together to create different shades of grey etc. Usually sprayed through a 0.35mm and 0.4mm needle at around 25-30 psi. I know you don't need to use thinners with it but i sometimes do and it sprays beautifully. Just make sure to give it a really good shake. Thanks again buddy. Keep up the excellent work.

Very useful video and answered a few questions i had. I really enjoy your videos thank you

Thank you for you tip's and how to video I am using a other primer at the moment I am going to stick with same make so I can get better then I will look around will keep this in mine. Thank you

I watched your air brush cleaning video... and I slammed the subscribed button and bell... You cover every aspect of a subject... plain and strait forward... Thanks for all your hard work brother... from across the pond...

I do enjoy your videos, in particular these tutorials

Great video Paul.... as ever great advice tips presented in an informative and entertaining manner...especially liked the avoidance crisps fingerprints ...lol

Took advantage of the UMP sale and glad I did :-) buying the cleaner and gloss black primer ..as usual excellent stuff my friend

Really good video Paul, nice attention to detail for all of us beginners to see how to do it right!....Bill

Thanks for the tutorial. I have been reluctant to buy and try but had some in a recent eBay job lot. Just watched this and tried the grey primer. Worked fab. No issues Used my harder steenbeck ultra with 0.4mm needle about 28 psi and results are almost flawless. If I was better at spraying it would be even better. More than happy with the results and when I need more I will definitely be buying more. And would definitely recommend the priner

Nice tutorial Paul. Just got to get a bench, compressor and airbrush now!!

Cheers Paul, just ordered your apex airbrush, need to get booth and compressor,

Love it when the black roof flashes to dry before your eyes, my number one indicator that I'm on the right track...

I am at my second bottle of Stynylrez, the blue one. 0.35 nozzle, 15 psi, 24-26°C, 50-70% humidity: not even a hint of trouble! More over, although it might seem a bit soft after curing, it takes the sanding beautifully. I am more than pleased so far.

Great video its perfect to show how primer color effect top coat color

Excellent tutorial Paul - the 'Bob Ross' of airbrushing. LoL......

The UMP primers are all I use, they are fantastic.

Nice tutorial we'll explained thanks pual

rewatching this, for some reason got it in to my head that I needed to thin (with UMP thinner) the primer... will try a larger needle and thin coats (I usually do 2 slightly wet coats (not flooded).... )

Another great tutorial to add to so many others you’ve done, thanks Paul. You’ve also answered a query I was going to research on and that is what precautions will I need to take spraying in very hot and humid climates (I’m in Singapore). I do have an aircon unit in my room so I can keep the temperature down a bit but the humidity is still a very big issue. Any other advice on coping with hot and humid conditions warmly (!) received. Thanks!

Are these primer okay under splash paints?

I just got my ultimate thinner, and finally got use the stynelrez. I can’t get it right. I keep getting chunky bits coming out and splattering on my air brush. I spat at 35 psi. Thin 50/50ish with ump thinner. I think the paint is drying in the cup. And I use my .5 trigger gun. I’m guna try the thinner coats with a .3 mm air brush. See if that fixes it.

Paul, another excellent video. But I do have a few questions. Being a car modeler, I nearly always use Gravity ,Zero, or MCW paints, which are pre-thinned, and are basically as thin as water. They each have their own primers which are as thin as their paints. When I learned how to use an air brush way back in the 1970s using Tamiya paints & primers , they were thinned 1:1. Watching your method, I was surprised that you're not thinning your primer, and instead increase the air pressure to 25-30 psi to compensate for the thickness of the primer. Basically it's 3 different methods that cover the thinning spectrum, and from what I can see, each seems to work just fine using lite, even coats. My reasoning is that the super thinned primers/paints are lacquer based, the Tamiya primers are an acrylic lacquer base, and your primers are a true Acrylic. And each of these bases are best air brushed at completely different thinning ratios. Just how far off base am I?

Thanks for the video, great tutorial. Would you spray the Glossy black primer the same way? Heard a lot of different suggestions on that perticular one.

Used this and tried the AK next gen over it and the AK paint it easily removed from the primer. wierd!

That looks a great colour scheme, with those 3 primers Paul. Do you still warm your primer in the baby bottle warmer?

Awesome👍🏻😎

Thanks for video I have just obtained some ultimate grey primer I afraid I have probably done everything wrong so far with it and I have ended up with flakey uneven coat can I rectify situation by just sanding G

Really enjoy your no BS instruction/review videos. Without having to check out more videos as I'm a bit pressed for time today but is Ultimate Primer suitable for use with Lacquer Paint?

Might’ve a bit of a daft question but can a hairdryer be used to help dry the primer between coats? Wondering if the heat would cause any issues? New subscriber btw.👍

This will help

Enjoyed hat video Paul, was watching an earlier video on your primers and you warmed the paint, do you still do that?.

what other cleaner can i use to clean the primer off the airbrush besides ump's?

Im asking coz i dont have Shop for Zero paints, italeri, tamiya etc in my area and for me is to expencive order it via Internet, i just have acces to Revell models and colors.. Sorry for gramatics and thnx for youre answer

Hi - great video but I'm wondering do you thin the primers down at all..?

Can i put vallejo flow improver with the primer or no

A little off topic but did you ever get around to finishing that Valencia Subaru with the gold speedlines? I’ve watched all the fairly recent bench updates and can’t seem to find any videos of it...

How long can the ump primer be stored in an unopened bottle? Planning to buy a boxes of them and ship it too a friend in Finland while England still in EU. He will then bring it to Norway with a car. Stay clear of customs and tax

Can you spray xtracrylix over the top of these?

Hi mate Can you spray zero paints pure brilliant white over ultimate primer?

What types of paint are safe to use over these as a base coat?

Hi Paul how long did you leave it before removing the mask and remasking ?

Can I use ultimate primer with tamiya lp paints

Can i use this with gunpla Ps: sorry for taking away ur time 😅

Whenever I see somebody do the backflow thing I die a bit inside... why not just flush it with some more water instead? You're forcing a tool designed to push air and paint forward do the exact opposite - push it backwards, that can't be healthy for the seals inside.

Paul, What is your average humidity in your cave?
