The Spray Painting Thread

[Rcubed]

Hi All,

As mentioned previously in this thread, I have a Toyota document called 'Fundamental Painting Procedures' [pub.no.36438e - printed 1984]. To preserve this booklet, i have scanned a copy of it and formed a 26Mb .pdf binder [completed with chapter bookmarks and the correct page numbering].

As it is illegal to use such a document, except for personal use as a backup, I am unable to distribute it, or sell it on eBay. However if someone would like to 'borrow' my copy for private use PM me with your email address.

cheers,
Ray

Thought I'd add a post to this thread,

A mate of mine needed a coat of paint on his liberty before selling it, so I got to use the car as a practise car before doing my mrs's levin.

The paint is just Motospray acrylic, it came out pretty good after a buff. I used a Devilbiss GFG-670 gun to spray it as my airline setup wasn't good enough to supply my GTi gun. I actually bought both guns from Ebay US and ended up paying what the local shops wanted for just the GTi gun...

I must say the Devilbiss guns are a lot nicer to spray metallics with than my old cheapo Scorpion gravity feed guns, no stripes in the paint at all and a good finish.

Here's the car prior to buffing:

Here it is after a cut but prior to polish:

I'm quite happy with the way it turned out, especially for $200 worth of paint.

Here's a shot from when we first started, bumper required a lot of sanding to get rid of prior crazing and I had to weld some new steel into both front doors under the mirror due to rust...

looks good to me, definitely one of the better homejob acrylics i've seen tops!

is it best to put a clear on a paint job? or can you get away with just the colour buffed out?

I'm looking at painting my car Lexus Blue, not sure if this is a clear over colour paint?

[-Totenkopf-]

I think that lexus colour would be two stage at least, ie, will require clear. IMHO, paint it CoB man or don't bother

Base colours like red, black, white etc could probably commonly be found in a single stage application, using a base that is meant for two stage application without the clear will end up in the shittest job imaginable. When you'll spray the base you'll notice it comes out a matt colour, ie, it isn't shiny. Only when you spray the clear does it gloss up. Bases made for two stage application designed to absorb the clear.

what he said.

put clear over it

As well as having a matt finish, you'll find that it almost washes off with water. The tiniest bit of solvent, even wd40 will wash it off like crazy. It needs the clear to give it gloss and to protect it.

Anything metallic will be a clear over colour system. I've sprayed a bit of 2k and acrylic and I can't recommend 2k highly enough. You need less than half the coats you need with acrylic and it's super shiny straight off the gun as well as being more durable. If you want, you can hire a booth for a couple of hundred an hour (you'll only need it for an hour or so if you prime and prep at home). That'll ensure you get a dust free job and lessen the chance of breathing the stuff in.

Having said that, it is very possible to get a great finish in your garage.

This can (and did for me) backfire.

I hired a booth the first time around. Because the owner of the booth no longer used it for his personal work it was in a bloody messy state, and ended up just blowing shit all through my paintjob.

It was a crap day from the getgo, it started raining as I had the car towed over there so I had to spend an hour or so blowing all the water out of the job. My mate who was doing the painting that day was running an hour or two late as well. The booth owner charged me not only for the time I was using the booth (maybe 2, 2.5hrs) but also the time I was on the premise. As it was raining out, I didn't end up getting a break in showers until about 5pm when I had the tow truck driver return to collect it (heh, it got rained on a little on the way home, the finish had been baked, but it was still fresh enough to water mark, not that it mattered much, the job was screwed anyway due to white shit through a black finish).

To top it all off, he also charged me from 8AM as that was apparently when I told him I'd be arriving there, when I clearly told him I wouldn't be there till around 10AM. My mate (who is a painter of MANY years) was out (getting a feed) when I approached the booth owner about price for hiring so I ended up paying a large sum of money for a screwed job as well as all the paint, materials & time I'd spent in prepping the car. My mate said that if he was there he would have told the owner to get shafted. I on the other hand like to avoid conflict where necessary. I was pretty depressed after the whole incident though and my bank account was left VERY dry.

Moral of the story, if your going to hire a booth, make sure you hire a booth that is still actively used by the owner, otherwise, its likely to be ill maintained and do more harm then good. Richard, if you were looking around for places that hire booths, gimme a tingle and I can tell you where not to go. Coincedently, the owner of this booth was also named Richard.

Thinking back to that day makes me wonder how I've ever managed to finish this project after all the disheartening and disappointing times I've endured. Any sane man would have thrown in the towel.

[af300e]

Fair call.

I transported a car to a booth in the rain once but I covered it with plastic drop sheets and taped it up firmly. After 50km at 100 clicks on a car trailer, we unwrapped it and it was perfectly dry.

Good advice though,plan, plan, plan. Even then shit can always go down.

If someone was to say, not effectively mask there windscreen when applying an acrylic clear in close vacinity and later realised they clear coated said windscreen. What would be the best way to remove this coating to return clarity to the glass?

thinners takes paint off glass pretty easily, or a razor and then lightly soaked rag with thinners if it's pretty thick

OOPS, yeah thinners on a cloth, and some very fine steel wool, sometimes a scraper blade will mar the glass.

cheers Chuck.

Soak some steel wool in some thinners (obviously be careful as to not allow any runoff near the areas you want to remain painted) and this will remove it nicely...

Edit: Q already answered by those above (would help if I changed to page 24 )

Just make sure to use a clean cloth free of any dirt or sand, one little spec of sand on the cloth and you will scratch your windscreen.

[GT1978]

Cheers guys I'll give it a go.
