Airless Sprayers
Just starting to restore my Kombi and want to do as much prep work as possible myself - I will be removing rust and welding in new metal, plus taking
the rest back to bare metal where I can
What I then want to do it put on some etch primer, spray putty, primer etc to protect the metal and prepare it for my painter to then do the finishing
work.
Will a Wagner Airless sprayer or similar be capable of completing this requirement - I am also considering a compresor/gun set-up but have limited
space and dollars?

An airless sprayer is not suitable to paint automotive paint as it does not atomise the paint enough. You will have a very orange peel finish.

Never used an airless on a car body but years ago I had an airless spray operation for commercial applications, machinery, large buildings, roofing
etc.. I could spray around 110 square metres an hour at 2000 psi all day long (OK, occasional blockage).. the gear I used was Wagner.. It had an
electrostatic application which I never played with but always wanted to..
Helbus, I think you'ld find that an airless unit will do a great finish on a car.. The atomisation out of the nozzle is dependant on the size/shape
of the tip and the pressure at which you pump it out..
However, as said, I have never attempted it and I think the standard Wagner from the hardware store is not suitable.. Our pumps were large truck
mounted units or wheel around jobs..

Thanks for the replies, so as per my original question I gather the sprayer will cope with primers, etc to protect the metal (which will then be
rubbed back and finished by my painter with 'real' equipment)?
Helbus - I am not too worried about peel as the main purpose is to get some rust protection whilst I complete the rest of the work needed (long resto
expected) - are you saying the paint is too thick for the airless sprayer to cope with?

primers and spray putty are too thick for that style of equipment. use a real spray gun with a least a 2mm nozzle. A large industrial style airless
would handle the job.

Give it a go. I was not sure of the finish you required.
In the vehicle refinish industry, Two pack is sprayed using HVLP (high volume low pressure) equipment to maximise paint transfer rate and lower vapour
content.
They also use this technique to paint new cars along with electrostatic charge to increase the tranfer rate even more.
I do not know of any refinishers that yet have used airless in mainstream automotive finishing & refinishing.

Sorry if I seem pedantic but he did state that he wanted something he could do himself to help protect it from rust before he had it professionally
painted.
It might not be used in the Industry but it does seem to fit his needs.

I agree, It will suit his needs, I was just unsure of exactly what the needs were at first. My fault. You may pour jelly crystals down my jocks if you
wish.

Thanks for clearing that up - finish is not critical at this stage - as long as the metal is protected from surface rust I can rub things back
later
I have run out of Jelly Crystals, but have some 5 minute epoxy lying around - will that be OK?:o:o:o:o:o:o:o

As for 5 minute epoxy. That stuff gets hot when reacting. Yeah? Wonder what id does when mixed with jelly crystals?
