The Spray Painting Thread

... if I prime with this do I need to top coat, given that I don't care what it looks like?

Then, no, you should be good to go with this.

I have been using step 1 of the Wattyl system for years now. A Windscreen fitter mate of mine uses the same stuff on cars. Any corrosion around a windscreen is just going to keep on going, he cleans off the area with 120grit paper then applies the kill rust. By the time he is ready to install the screen the rust converter has done its job. Normally there is no time to apply a coat of colour, but when we did a screen in his Hi Ace, we coated that Wattyl Killrust with acrylic primer and 2pak topcolour.

etc.

Ive got a 2.5 hp 15 cfm compressor and was told that was the minimum requiremnt to paint a car. most ones you see in supercheap will not really do the job. only good for inflating balls and pools

I once used one to re-fasten my boat (with the air drill) and then paint it. We're talking 4000 stainless steel screws and a 10 metre launch, Was upto the task once I worked out to remove the top of the switch and wind the air pressure cut off up a tad, For spray painting you set the outlet reg to around 25psi and be sure to have an air drier in line. It will keep up but remember it's mostly in the preparation and the paint mix and this is one case where you really must follow the directions and keep everything clean. Practise does come into it so old panels first and go from there to get your own way of doing it right. But then you have the satisfaction of knowing you did it yourself

Dang. "Suitable for interior and exterior use, however must be overcoated."

Taff, I replied to a thread "If you use a cutting compound paste, you can wet it down a bit to thin the mix and make life easy. Use a trigger spray bottle filled with water add water as required. Old "T shirts"are the best material for hand compounding, just keep on turning the cloth, as the dry build up will scratch your paint. Microfibre cloths are the go for final shine.

I need help!! Don't know what I was thinking when I decided to use cutting compound paste on my wife's 2006 Astra, I was putting it on wet, but I let it dry and this is where I went wrong, I wiped it off when dry.... I scratched the Clear coat.....
What is the best way to fix this? is there a way?

Thanks...

More cutting compound in same spot and done properly I would think.

There are generally several levels of "cutting" and "polishing" formulas - Light Swirl, Heavy Swirl, and eventually Cutting Compound. Each of the major manufacturers have product like Meguairs, Mothers etc.

Wash the car first.

I would use a ROS (Rotary Orbital Sander) with a white or orange pad and high cut (or Heavy Swirl Remover) formulation to remove all the scratches and then follow this up with a Light Swirl Remover on a black pad, again on the ROS. If you are unsure, start with the Light Swirl Remover and see if that does the job - if not, go to the Heavy.

Finish off with a Glaze or Wax to seal the shine.

Someone decided to key my wife's new car a year or two ago and using the above I was able to completely remove any sign of the scratch so you should have no trouble with what you've done. Obviously, if you have broken the paint surface you'd be in trouble but I don't think that's the case with you.

The above method is fine for metallic paint?

My wife's car is an Honda Accord Euro with metallic paint (Dark Grey/Charcoal colour)

Number one rule when cutting and polishing, "DO NOT DO IT IN DIRECT SUNLIGHT/HEAT" You have to do the cutting and polishing in a garage or a carport at least. Make sure the surface is cool before applying any compound. Open the bonnet of the car to allow the engine to cool before you attack the bonnet. Do the rest of the car before the bonnet. Work in small areas at one time, 600mm X 600mm is almost too large an area. Trying to apply compound to a full panel then removing will inevitably end up up in mega scratches.

Jeri follow Peters guidelines, and you should be able to repair the clearcoat, however, if the scratches are deep gouges as though someone wiped a rock filled rag on the car, then you will have to wet rub with 2000 and 3000 wet and dry sandpaper then cut and polish.

Just spent the last 3hrs applying underbody sealer by brush. Never Never again, what a pain in the Ass. Normally I spray that stuff on, but the car was blocked in by other vehicles, so bit the bullit and brushed it on. Biggest problen is you cannot get to some places with a brush, whereas the shultz gun just sprays everywhere you need. Spraying only takes 30-40 minutes.

Hi guys,

Going to paint the bumpers on my TA22. They are currently chrome and in pretty good condition. I am unsure of the exact process to take with these chrome items to ensure good results, but here's what i've got so far:

1) Sand the chrome suface back using 180grit pad on orbital sander... Do i need to go smoother?
2) Apply U-pol Acid-8 1k Etch Primer (have a tin of this).
3) Apply Concept Paints Acrylic 2-in-1 Primer/Filler over the top.
4) Guide coat & sand, tidy up any low spots.
5) Apply top coat (acrylic)

Does this sound about right?

Thanks for any help.
