the nobs dropping off was acording to our Iwata rep an issue created by waterbased thinners it has been addressed withe the EVO version of the Supernova ,to increase aplication speeds tweak the fan down slightly
the new Bellaria is supposed to be the gun for those who want the supernova performance without the cost and much cheaper to service
[quote=”Mal” post=31500][quote=”ARTSPRAY” post=31493]ah so thats where to get that torch its not available seperatly ,have you got a link to that set for me mate[/quote]
It’s usually just the cheap 14.4v drill outa B&b / homebase etc with chuck and motor removed.
Cheaper

ah that explains it ,thanks matei use feestool DA great tools ,but do take a look at Solux bulbs they are what is in the Sungun ,thers a seller on ebay who doese a Solux fitted rechargable torch for £65 inc a spare battery but as i say you cam make tthem for yourself anyway ,BTW whats the lazer pen used for ?
sun gun is a con you can buy the solux bulbs for about £6 each and fit them to a 12v rechargeable torch yourself ,IR temp guns are cheap as chips off ebay or from Maplins ,elcometers will cost but you realy need to think about why you would actualy need one as you cant tell how thick the clear is with one anyway they realy only have a use in the paint aplication process ,it only tells you total paint thickness so if the primer or base is thick and the clear is thin your not getting any usefull info anyway as it is only ever the clear you need to be concerned about
oh and for detailing you dont even need the sungun or solux bulb a Brinkmann Xenon torch will give you all you need for under £50 ,sunguns are only required for colour matching ,so unless your doing a bit of SMART repair as well you honestly dont need one
i often use my sata minijet 1.2 for clearing bumpers ,halves material usage but i would highly recomend the Iwata W101 or the centre post version the W300 1.3 if you want to put in on faster and wetter ,your material usage on panel work is vastly reduced using mini and midi guns however often the finish is a little too good ,another great gun is the ANI R1 HPS 1.2 also available as a Draper expert ,you can pick them up for about £100 and they will blow the Sata mini into fits for clearing
As indicated in Table 1, a negligible difference was found between the TE’s obtained for HVLP and conventional air spray. Information in Table 1 suggests conventional air spray equipment is capable of achieving a TE comparable to HVLP while operating at a slightly higher fluid delivery rate. The volume of material used by each spray gun to finish the panels was also relatively consistent, ranging from approximately 6.3 to 6.9 ounces.
Another significant finding of the comparison was the finish quality achieved with each spray gun at different fluid delivery rates. As shown in Table 2, the HD panels (sprayed with the HVLP spray gun at a fluid delivery rate of approximately 3.6 oz/min) consistently ranked last for smoothness. A noticeably higher degree of orange peel was present on the HD panels. The panels identified as HC, CD and CF were comparable in appearance with respect to smoothness. This is reflected in the inconsistent ranking order assigned by each staff person and from staff comments on how difficult it was to rank these three panel sets.
In regard to gloss, the HC panels consistently ranked lowest. Again, based on the inconsistent ranking order and staff comments, the remaining panel sets (HD, CD and CF) were comparable in appearance.
Implications
The comparison study findings suggest the following in regard to TE, finish quality, production speed and fluid viscosity:For higher viscosity coatings, conventional air spray guns may be used just as efficiently as HVLP spray guns if they are properly set up and operated. As Table 1 indicates, conventional air spray guns are capable of achieving TE’s comparable to HVLP air spray.
From a finish quality perspective, conventional air spray equipment may be the best choice for high solids/viscosity coatings and production rates. As illustrated by study findings, the higher atomization energy levels available to conventional air spray equipment make it better suited for atomizing high viscosity coatings at higher fluid delivery rates. Consequently, conventional air spray guns may produce the desired finish when spraying high performance high viscosity coatings in a production environment while the finish produced by an HVLP air spray gun may fall short of expectations. As indicated above, this may be achieved without sacrificing TE.
Findings suggest that HVLP’s reputation for TE may simply reside in the fact that its design lowers the ceiling for excessive setup parameters, a particularly beneficial attribute when spraying easily atomized coatings. That is, when compared to conventional air spray, HVLP design restricts the degree to which operating parameters (i.e., fluid and atomizing air pressures) can be set to excessive levels. While advantageous for low viscosity or easily atomized coatings, this attribute puts HVLP at a disadvantage with more difficult-to-atomize high performance coatings.common misconception due to bullshit from the industry many years ago when HVLP was forced onto everyone ,HVLP has lower transfer rates with higher viscosity materials as it lacks the air velocity to keep the droplets in flight ,reduced pressure AKA compliant guns achieve higher transfer rates with high voscosity materials ie clearcoat ,even old conventional equipment is good with high viscosity materials ,its just not that good with bases and thin paints ,thats where we where all conned 😉
basicly your using the wrong gun for the aplication of clearcoat ,if you want it to put out less paint then simply turn in your fluid control nob an reduce the fan down to compensate ,readjust your inlet pressure to optimise atomisation and away you go
