    Default Q4 Re-spray pictorial

    Sorry to those that visit the other Alfa sites, you may of seen this before:

    I am starting a full re-spray project on the Q4 and will document the progress here and on the 155 forums. Never used a spray gun before so not expecting gleaming results but will hopefully look OK.

    Wash it:


    Rub down bonnet (600 grit W&D):




    De-baged and De-Spoilered (it's a heavy bugger. The boot lid is light as a feather now! ):


    De-Skirted:


    Found a crack in the paint pot - so very glad I found it the easy way! Have emailed the company the pic:


    DA sanded on a big chip in the paint:




    Will be a pretty lengthy process and will post pics as I go..

    Good luck Jack, where are you going to be doing the spraying? In the garage or a are you going to rig up a spray booth?

    Only ever done a little spraying before, prep and patience and you will do fine.

    Going to be spraying in the garage - not the ideal place but should be OK.

    If you grab yourself some large decorators plastic dustsheets and some duck tape you should be able to rig up a fairly decent spray booth. Be worth it given all the effort you are going into in prepping the paintwork.

    Not really unfortunately. Maybe more this weekend then things get busy for many weekends after that.

    It is off the road now and will be sorned for a few months so I can do it slowly.

    Have rubbed down all of the off-side and bonnet, plus skirts, a new mirror.

    Going to remove the bumpers next and spray all these bits separately then roll the car in the garage.

    Where is the honeymoon then? Persuaded her that a motoring tour of northern Italy would be a good idea, or going to loaf on a beach somewhere?

    Bit of an update - have actually sprayed some paint now, all-be-it primer:



    Good side, nice and solid:


    Bad side, mounting point is solid so will clean up and put some rust stopper on as a temporary measure:



    Bumper was a bit buggered but now riveted back together with metal plating on the inside:








    166 bumper for some practise:

    Looking like you are getting on well with things Jack. How are you finding the spray gun? Can't see any runs on what you've done so far.
    I've always fancied having a car finished in primer grey, tempted?

    Hehe, not that tempted no

    Spray gun seems really good except it has given me a pretty big blister. I was using one finger to pull the trigger when there is space for three.

    No real runs yet, might be a different matter when the colour goes on!

    Some more.

    Painted up the wing and other trim bits. Not sure on the finish I have got though - I thought it was OK (given I have never sprayed colour on anything with gun before) and that it will flat back smooth for a good polish but my dad says I can get better - smooth finish out of the gun? Don't know what to adjust really. The finish is consistent all over.

    jack, isn't that 'orange peel' effect as we call it here cause by spraying too thick a mixture? The paint will produce runs easier with a wetter mix, but will have less orange peel..

    Looks like orange peel to me as well. How far from the panel are you holding the spraygun, and what was the temp when you were spraying. Looks like there wasn't enough thinner in the paint when you sprayed it or too much of the thinner evaporated from the mix before it hit the panel.

    Just my 2p

    Interesting colour there, why isn't it in the forum garage? Get it stuck in there.

    You should be able to save the paint you have done so far Jack, but its probably best trying to sort out your mix\settings\technique for the rest of the panels.

    Shouldn't you be planning a wedding as well, not hiding in the garage?

    I'd say the orange peel effect is being caused by the compressor running out of steam, it's what I would call "dry" rather than orange peel. Let the compressor charge up and don't paint to much in one go.

    You'll be needing to get a buffer and polishing compounds like G3 and G10 to cut the paint back to a super slick wet look, that where the real skill is. Many a poor coat of paint is saved by the polishers skill.

    Flatted it back tonight and turned the pressure down by 20psi - was a touch high for a HVLP gun. The finish now is much better

    The compressor is a fairly big beast so doesn't charge up too much.
