Going to dinitrol the inside of my galv chassis.

Problem is I don’t have a compressor with a tank. I do have T max HD compressor can I use this to power a cavity air spray gun? Or would I need to get a separate tank to use?

Have you bought it already? You can either buy trigger gun with lance or aerosol with lance?

I’ve had the compressor for ages. Haven’t bought any dinitrol yet but the aerosols looked like they had short lances and I figured an air powered gun would be better

oooo is that right? I’d rather do it via aerosols. Saves money and I don’t use air tools anyhow.
 
Yeah it’s decent. It’s a long flexible lance with a fan spray bit on the end. Feed it all the way on through holes then draw out slowly. I’ll do defender some time soon hopefully. I’m going to use dynax on internal then their underbody wax ontop of my paint on external

And it’s got a decent lance? I had a few long lances off eBay for something else that were sh!t

how many cans did you end up using?
 
I was actually looking for the lance earlier. I had one from dinitrol too and that was decent. Dinitrol on inside of my 90 bulkhead where I couldn’t paint below screen after having a leak and inside a pillars. I do like dinitrol but I did my d1 with dynax and 600mm lance. When I looked down the end of chassis it had thoroughly coated what I could see with a nice coating. I rate all their products to be honest. Electrox is amazing, albeit expensive and their epoxy mastic paint is soooo tough!
 
Dinitrol ml seems to heal a lot runnier. Apparently dynax ub is even self healing if bashed! The dynax s50 settled nice and thick inside d1 chassis. I think bh are the best out there now to be honest. I’ll be doing my chassis in electrox, then epoxy mastic, then dynax in cavity and dynax ub over the paint

Maybe I’ll just do that then. A lot easier.

The best way, which is tricky when it’s your daily, is to clean out all inside with pressure washer drain cleaner, leave to dry and perhaps widen up some holes for drain holes (my 90 chassis is full of mud). Once dry, work your way down the rails with dynax. You feed the whole lance on, then draw out slowly with finger on trigger to cover all. Then you have best chance of it sitting on chassis and not silt

Thanks for the tip mate. Will get a jet washer in there!
 
I’m assuming I’d need a tank and some kind of regulator if I wanted to use that compressor to power air tools etc? Has anyone done that?
 
Most air tools use a lot of air which needs to be delivered at sustained high pressure.

As an example, a typical air impact wrench needs 90psi at the gun & 18 cfm (509 lpm). That's garage size compressor territory.

Trying to use them on small compressors with small air tanks (receivers) invariably disappoints.

My own 2hp 50litre will crack one not-too-highly-torqued-up wheel nut before it needs to refill itself. Great for spinning them off after they've been loosened & spinning them up before final torquing but that's it. Utterly crap for V8 crankshaft bolts!
Fine for small SMART repair gravity feed sprayguns & will JUST handle a full size gravity feed gun.

Without a tank I think you would be wasting your time.
According to the blurb your T max 'Pumps 70 Litres per minute at 30 PSI'.
 
Garden sparyers work well but you need to thin and use an old one as it may never be the same... They are good becuase they are airless so you don't blow half of it back out.
