Superb primer at a super price
This is really good quality primer spray paint. It covers well, dries quickly and is superb for painting over acrylic paint. I'm using this on wood and stone. Fantastic value too, a full 400ml for less than half the price of its competitors. I shall be getting the black and white primers soon. They will be most suitable for the miniature models I intend to get to keep me busy during the cold dark winter months.

Covers very well and nozzle doesn't clog up at all.
A superb quality spraypaint which covers very well - also dries quickly. Most importantly the nozzle never clogs up unlike quite a few of the well known brands. The satin black version is also excellent and just as easy to apply. Been using these paints for many years now and never had a problem.

Makes paint finishes really smooth.
My go-to primer for most things, I mostly use on MDF blanks or 3d prints, using this primer before painting really makes a difference to the overall finish. Primer does have a bit of a weird smell compared to others, but it’s not too big of a deal.

Good primer easy to use.
Worked a treat used it to prime a gold door handle and letterbox so we could then spray paint it chrome. It did the job really well and was easy to use .

Hydrophobic - Issues
I used this paint as a primer for scale miniatures, and while the paint went down on the model well, having good coverage and colour, I did find that when I went to overpaint the primer with acrylic paint it was exceptionally hydrophobic. Having used the topcoats previously with other primers, I know this is not the issue. It was like trying to paint on bare plastic that hadn't been properly degreased.
