The Spray Painting Thread

["Z" UTE]

Taff, the easiest paper to get hold of is the stuff in a roll at Bunnings, has to be the white one (aluminium oxide) as this one stays sharp longest and resists clogging. The stuff off the roll also fits on the long boards, whereas sheet paper is limited in size.

As for primer shrinking, if you lay it on really wet and thickly that will happen. The trick is to lay down only as much as you require.

In my application of primer just before colour coat, it is more of getting a uniform colour and a nice even bonding coat. Lotsa people do not realise that you can buy different colour primers and different colour hi fill. If you end up with a patchwork quilt of these colours, you may have a blotchy looking finished paint job, depending on the solidity of the top coat colour.

Chuck,

I have my TA22 in primer/filler (Concept Paints Acrylic 2-in-1 Primer/Filler) as of last weekend. From what i've been told it's now time to apply a guide coat and start blocking back the imperfections.

I'm wondering what type of paint to use as the guide coat? The Primer/Filler is acrylic and grey in colour, applied with a HVLP spray gun. I will be applying a Acrylic top coat at the end of all this... if that helps.

From what you've mentioned above, you said you wouldn't use a spray can paint under gun-applied paint. So i should resist the temptation of buying a spray can based acrylic black paint and using that?

Also, when blocking back, if it looks like some of the low spots are a little too "low", what's the best way to proceed? Apply more primer/filler in that spot? Use a thin coating of glaze putty (if so, can you recomend one)? Something else? I have a feeling a couple spots may be an issue, and would like to know what the plan of attack is in advance.

Thanks in advance,
Dave.

SHEPPO, this is the one exception to my spray can rule. Use black acrylic, hold the can 12-18 inches away and give the car a dust coat, most of the thinners(which are the problem in cans) will have evaporated by the time the mist hits the car. You will be sanding all of this off black guide coat off, so no drama's.

for small imperfections a spot prime with primer filler will do the trick. Fill the really low spots with a very fine 2 part filler, avoid the blade putty for anything deeper than a bees dick, as it shrinks back massively. I use Galvaplast Microfine Filler, from my PPG outlet.

If you expose pimples of metal in the sand back process, you simply knock them back below the surface with the dimpling hammer, and apply a little filler to cover the new low spot.

Is there anyone in Sydney who's handy with the spraygun? Everytime I go to do the last coat on my car, something fucking bullshit happens. I can pay but dont have much as I'm not working atm. I have a good compressor, new gravity gun, and the paint...

Hey Z Ute I am thinking of getting my car painted with truck grade paint considering I do many trips from Sydney to Albury on the Hume Highway and get many bugs on it.

If I take the truck paint to the smash repairer will they complain about applying it or does it flow like regular paint?

What makes it hard wearing?

Will they be able to use PPG clear coat on it?

What brand of hard wearing truck paint can you recommend which is not PPG (It is quite expensive)?

[SHEPPO3930]

My company manufactures semi-trailers, road trains, etc, and we use "Glasurit" brand 2 pack paint on top of an epoxy primer. The stuff is insanely tough and VERY resistant to stone chips, doesn't mind being washed with high strength truck wash, etc.

What's the finish like look good when clean? Z Ute what you think about my questions?

["Z" UTE]

Glasurit is a really nice paint to work with, but can be more expensive than PPG.

Most trucks you see on the highway are painted in a polyurethane 2pak paint, Glasurit, PPG, Dulux, etc

See if your PPG supplier has Autothane 2Pak, which I think is the trade equivalent of PPG. I have used it many times, three coats of this stuff is like 5-8 coats of acrylic, and it is as solid as.

Your painter should not have any qualms about using it, you will not need to clearcoat this stuff if you use a solid colour.

If you want to use a PPG clearcoat, you can use a basic and quite inexpensive acrylic base colour under the clearcoat. Commonly called COB, (colour over base).

Be warned though that most painters use a particular line of product from one manufacturer, they are accustomed to using that paint and are capable of getting the best results from that paint, due to their continual use of the product. So have a chat with your painter, if he is at all hesitant about using the product you want to use, ask him for his product recommendations. Then do some research on that line of paint before commiting to that shop and that paint.

cheers Chuck.

Thanks for reply. You say if I use a solid colour like toyota red I won't need to clear coat it. I want the car to have a shiny clear coat when its clean. Is shine dullness a disadvantage of using truck paint without clear coat?

Considering how tough truck paint is I suspect it is not damaged very much by bug bits and bird poo. I always viewed clear coat as the protective layer for normal automotive paint against bird shit and such.

Absolutely correct a good clearcoat will give great protection, on a base coat colour. However a 2Pak solid colour will contain all the clear you need without having to cover with additional layers of clear.

2pak solid red will be as glossy as all get out when applied corretly, so there will be no dullness whatsoever, and no need to apply any clearcoats.

So why don't many people painting with solid colour use truck paint on cars? Is it considered overkill?

Is it also overkill to apply top coat hardner over truck paint?

["Z" UTE]

"Truck paint" is 2pak, and as with all 2Pak requires special facilities and equipment. The average backyard painter will use acrylic due to lower cost and lower health risk levels.

As far as applying top coat hardner over truck paint, that has just left me totally confused, never ever heard of that being done.That is not how a 2pak process works.

cheers Chuck.

My fail either way thanks for your help mate. You sure do hard work answering the same kind of painting questions in this thread over and over again.

[nuk1ear]

does anyone know a place around eastern/south eastern melbourne suburbs that do acrylic paint matching? I have a tin of the colour i want in 2 pac, or is it best to take the fuel panel off, polish it up and use that for a colour match?
