[elanjacobs]

I will have to work indoors

I hope you have a good gas mask so you don't end up killing yourself with the fumes....

Hi Arron what happens if I get the Orange Peel affect, will that come flat in the buffing stage?
I know I can get the festool compounds, what grit they are I don't know until I email them, as for any others I will try our local spray shop, but they don't speak any English, so it gets a bit hard at times.

Hi Woodpixel, I've found a place in Thailand I can buy 3M products online, but everything is in Thai, the compounds are no problem, they sell PN 36060,
PN 06094, & PN 06068. I see you use a Festool, I also have a Festool Rotex RO 150, my question is, would the 3m foam buffing pads fit straight on the Festool, or do you need an adapter. Or should I buy the festool pads?.
Thanks

Yes and no.

Obviously the preferred situation is to have sufficient skill to not get it in the first place. Generally some measure of tweaking will eliminate orange peel - orange peel means the product is not flattening out suffiently so generally fiddle with the mixture (ratio of thinner to product) as your first step.

A possible solution if you get orange peel is to spray it over once or twice with pure thinners. This remelts the surface and allows it to flatten out. Test first - sometimes it works, sometimes it doesn’t.

Otherwise, just spray another coat of product, but make it thinner.

If you can’t do that, then remove it in the buffing stage. Sand with 1500 grit till all the dimples are nearly gone. Buff with coarse compound, then fine.

On another note, I’m not a big fan of spraying indoors, even in makeshift ‘spray booths’. Outside, with a respirator, and with a clear line of breeze is my preferred setup. Choose a low VOC product and have some regard for your neighbours.

One can always order 3M off Amazon

I use the RO150, which works well, but I'm a bit cautious about it ingesting the goop (one can't turn off the extraction native to the tool). I bought a cheap random orbital polisher off Ebay just for it. The small velcro base pad winds on and the waffle-pads then stick to it. It has a 0-9 speed dial and the action is a true random. This stops swirls and holograms in automotive paint. The pros use a bog standard rotary one with a huge wheel, but I don't have that kind of skill.

BTW, the foam pads are nothing special - the 3M are cheap and last forever. Just don't mix up the pads with the compounds if you are doing a car!

edit: Found it! I bought it in 2011, but an old email had the info. A quick google and it is one of these: https://www.amazon.co.uk/230V-240V-A.../dp/B00KNJJX74 its a dual-action random orbital sander. It's a noisy bugger, but it does a great job.

Btw Woodpixel, you mentioned Septone, Supercheap Auto is no longer stocking the stuff and the stores here have already run out of it. I’ve just bought a couple of 4l cans online.

Hi Arron, Thanks for your reply I will have to work indoors, I'm not officially allowed to work in Thailand, the police know I do a bit, but turn a blind eye has long has I don't flaunt it, so working outside is out.

working indoors is very very unwise.
apart from the explosion hazard, you also need to worry about the toxicity of the materials you will be using.

at the very least try and arrange a "proper" spray booth -- adequate air flow and filtering

SPRAY BOOTH - I bought a plastic green house from the garden section of Bunnings. Does a pretty job, and pretty cheap.

你在谈论的是一个涉及面板家具的过程。纯油漆无法达到镜面效果。第一砂光机。和曲面振动磨光机（重）这个规格。板材的基本加工，然后底漆，当然，涂装机是最好的选择，然后反复打磨，用底漆打磨机，然后在喷涂前喷涂三遍，然后这个过程结束之后，你想要的效果可以实现。

....
What you are talking about is a process involving panel furniture. Pure paint cannot achieve a mirror effect. First sander. And surface vibration grinding machine (heavy) this specification. The basic processing of the board, then the primer, of course, the coating machine is the best choice, and then repeatedly grinding, using a primer grinding machine, then spray three times before spraying, and then after this process is over, the effect you want can be achieve.

I see the cold hasn't set in yet and affected your translation skills.

Just the cold frozen soul of Google Translate....

It's a bit nippy in the studio the last two days. The freeze is settling in (zapped my chillies!!!!) and making the fingers a bit stuff.

Not good for painting!

First time post, but you guys need to stop assuming and giving advice. Spray thinners to get a flatter finish? Omg get a clue.

You should be saying you will always get orange peel off a gun. To get it looking like a mirror all you have to do is make sure you have enough clear sand it back staring with a 1500 grit then go all the way to 5000.

It’s not like getting a mirror finish is difficult, it’s basic , it’s not witch craft.

You revived a 2 year old post for that? You could have said the same thing without coming across as a massive douche. You won't make any friends here with that attitude.

Also, looking at your post history, this is your 3rd "first time post".

Pull your head in.

Im with elanjacobs on this one what a comment to make you are a faceless warrior or to put it mildly a gutless individual who hides behind your computer.
