Harder and Steenbeck Infinity CR plus.

Well here is the H&S Infinity CR plus, I went for the CR plus because it's currently about $12 ( Aug 2014 was $30ish when I bought mine) more than the stock Infinity so a great chance to see what it's all about. The CR models have the triple chrome coating and tri needle seals. The extra chrome is for allergy sufferers they say but apart from that it is smoother and shinier inside as well as being more chrome colour than the Silverline and cleans up a fair bit easier to, by that I mean paint and thinner seems to wipe away easier with cotton buds etc inside (mainly) and out which is another plus for the smoother chrome finish, Don's pipette pump cleaning method seems a lot more effective as well. Here is how the Infinity CR plus (left) and the stock Silverline paint chamber compared side by side.

The photo on left is with just natural light, the right is a little led lighting. I'm sure theres a good reason why they make the two different versions but for a $12 difference I would just produce the CR plus models myself, anyway for $12 I highly recommend the CR plus models.

The three needle seals last longer and also make a tighter seal between the rear of the brush and paint chamber, keep in mind you can buy the 3 seals and the housing to suit them for less than $10 and it will fit all H&S brushes except for the Colani.

The Infinity has the adjustable trigger which has a simple to use, out of the way external screw and has a pretty good range of tension. The quickfix handle also works very well and lets you switch between unrestricted and adjustable preset flow of paint by a needle stop, it reminds me of a Swiss army knife when it clicks, has a quality feel about it but then so does the rest of the brush as well.

Now as for how it works, as I always do I used it straight out of the box with the .15 setup and it just worked beautifully first up with my Humbrol enamel about 70/30 mix and as with the Silverline I had the best control out of all the brushes I have used. Painted a few parts on a M113 and then had some fun on a few scraps, I had no problem spraying a lot of very thin consistent lines and various size dots and even a pussy cat.

Overall I love the Infinity as well, it and the Silverline are VERY similar to use and the main body's are pretty much identical inside and out "I think", but the extra couple of features on the Infinity and the gold and red parts are a nice edition for customization and make it look very elegant.

As of Feb 2020 this is still my go to brush and added the FPC air flow valve which is very handy.
