    Default spray painting....it's an art

    This post is for anyone who is wanting to repaint their ride, but lack the experience or confidence.
    Firstly, and most importantly, your mistakes build your experience so if you think you can do it... have a go....you WILL make mistakes, but if you choose to learn from them, you are well on the way to becoming a pro painter and you will also realise why good paintjobs are very expensive, you will understand the enormous amount of labor required in dissassembly, repairing, smoothing, washing with water then solvents, resanding over and over and if it's to be a show finish, all of the above multiplied by 10!
    How much does it cost? Well I'm doing one now to showroom finish in acylic which it was originally painted in, for nothing because the client is rebuilding the engine, for nothing.... bartering can be helpful lol. About $2000 to $150,000....no bull.
    The average cost in Australia for a good repaint in Acylic with 7-10 coats including clear is approx $8000-$11,000 though you can get it cheaper if you and your mates do it but you need to be experieced with car repaints.
    For the inexperienced wanting to have a go, practice on an old hood first, paint in black solid and don't even think about going any further till you have a surface so glossy that you can almost shave in it.
    Not all painters even very good painters can do the entire job on their own, so they employ others to do the prep and quality detailers to do the cutting and polishing processes.
    You may have heard ppl say that prep is the most important part of a paint job but that's incorrect. Each of the three stages are as important as the other, and each requires for a show finish a true craftsman at the top of his or her game.
    I'll try to answer any questions you may have but remember, I don't know everything about paint because if i did I would stop.... I'm constantly learning, and honing my craft

    I'm half way through painting an enclosed box trailer at the moment that I will be using to cart my band equipment around in. It was painted in what I thought was enamel but turned out to be acrylic so a quick clean up became a bare ,metal respray pretty quickly when it all fried up after applying a coat of primer. I'm painting it with Palais white acrylic because I already had 4L in the shed from another job I ended up sending out to a pro. It will prob get between 4 and 5 coats of colour, will that be enough?
    I also have 4L of acrylic clear there should I bother with it or is it not really required? Not really too concerned with a mirror finish on it because it has a few dents ad scrapes from a hard life.
    It has 2 coats of white on it so far but it was getting way too hot to finish it so I had to pull up stumps to finish it later. Hoping to get into it early tomorrow morning before it gets hot which will then bake it pretty well in the 40 deg heat that's expected.
    Also, is a 1.8 tip ok? it's the biggest I have. In a de-belviss gravity fed HVLP gun.

    Why would you bother with acrylic unless it has to be 100% original? I cant paint but I got some cheap 2k single stage and blasted it on a bonnet with a cheap $50 gun and it turned out alright glossy off the gun.

    I am waiting on a better gun that I ordered from UK and I'll try some clear over base 2k black or red next time.

    Because 2k is toxic and shouldn't really be sprayed outside of a ventilated booth from what I understand.

    ha.. done 5 full car resprays in my life 4 in Acrylic, one in Enamel (well it was an FJ sedan)
    (and that's enuff )

    plus lots of touchups... under bumper panels, mirrors etc
    and
    the only thing with these is PAINTING PLASTICS.. even with the right prep
    and paint PRICK OF A JOB colour matching them

    was lucky that I knew a guy who owned a panel shop (pretty well known here in Melbourne
    in the 70s for show car stuff... Bucket Panels)

    one effort ... which by the way had NO clear coat (just 8 coats of acrylic)

    2k uses a hardener to create the chemical reaction which hardens the paint (thats why the name 2k or 2-pac) and this hardener contains isocynates.
    Isocynates are known to cause cancer etc etc. And that is why you want to spray in a booth while wearing a mask that is feed fresh air from an outside source (such as a compressor outside of the booth).
    There is other stuff that is dangerous, but thats the main one.

    P.s I was an auto refinisher for almost 4years before taking the safe switch to parts supply.
    I plan to live at least 20years longer than previously planned now.

    Yes, but if you are paying for a job unless you have to go 100% original paint for some odd reason why would you not go to a 2K? That was my main point.

    They have respirators, and a lot of people do it in sheds and garages so you take your chances regarding legality etc.

    Hi cross8,
    Thanks for your questions. A few things first, the Devillbis hvlp is my gun of choice because of it's versatility and durability. For acrylic, I recommend a 1.2-1.4 tip and leave the 1.8 for when you move up to 2k paint systems.
    You show maturity with your patience due to the extremely hot temps, so you're off to a good start, though you can use a little retarder in your thinners to slow down the "flash" if you wish, to maintain good gloss characteristics and the end.
    4-5 coats is ample, just wet out the last coat to 1:1.5 or even 1:2 to even the surfaces out and aid the compounding that will follow.
    I'm not familiar with Palais white atm, so if no metallic, no clear is needed although unless a customer insists on no clear, I always throw on at least 5 clearcoats for two reasons, deeper gloss and more protection of the colour coats.
    I hope that helps and I think you will do just fine.

    If you're paying a shop to do it I'd go 2K too, just not keen on using it at home.

    Have a look for the technical data sheet for your paint, if you read the TDS for other paints they will usually recommend 1.8-2.0 for Acrylic paint, and 1.3/1.4 for 2K Single stage, base and clear and 1.8-2.0 for 2K Epoxy/Primer etc.

    I went ahead and gave it a shot. The new gun and the cooler temps made it a pleasure of a job! Comparatively anyways. It came up pretty good, certainly plenty good enough for a box trailer that's just gonna cart band gear around. Not too overly concerned about gloss. May give it a rub in a week or two just to make it smoother and easier to keep clean if nothing else. Thanks for your assistance gents!

    Thats the problem with acrylic no gloss off the gun, I've sprayed 3 cars with it and bits and pieces etc and its a lot of work sanding and polishing. When a half arsed job with 2K direct gloss came up a lot nicer with a lot less effort.
