. Just need to do it outside because the  :angrywife: don't like the smell of the filler when I'm mixing it in the garage.

Masks make sense with epoxy resins and MDF , when sanding an when mixing/applying . Dust-mask for sanding/cutting and carbon compound filter mask for mixing , applying or spray-painting . 

I buy these from Pienaar bros. in Paarden Eiland , you'll see that 3m list other retailers on product page .

Thanks [member=15834]FranZAR[/member] for informing this morning that my post went a bit sideways last night. Photos didn't post. Glitch or something in the system.

And don't forget the gloves [member=13623]fredeb[/member] . With covid all this got handy for building stuff. Especially mixing filler and sanding because the dust dry your hands. Got boxes of dust masks to. Just need to check where my carbon mask is for spraying but thanks for the heads where to look for if I need to replace mine.

Did some filler work last tonight and my compressor arrived to. Was standing at my parent's house for some time and got use there. Now just to wait for rite day to do primer. I just need to build some stands for the speakers to make it easy to move when spraying.

Some photoshow Wilson Audio do work and build stuff. They use white marine gel coat for it's first base coat and primer to make the box robust to moisture and bumps. I wanted to use gel coat but decide against it because I never used it before and it can go horribly wrong and harden in the spray gun.

It was time to retire my father trustee 28 year old Asturo spray gun and got two of my own guns. The Nova 1 is for colour spray painting and the blue one is a cheap gun with a 1.7mm tip for primer work.

Now just to wait for warmer days to come.

So Wednesday and Thursday we had some warm weather in Cape Town, so decided to prime the tops and bass units to seal them off. I picked up that the mdf don't like the cold wet days we got in cape town so they expanding standing in the garage. 1L of primer used. They need to be flat and more primer. It's all in the prep work now and allot of dust.

I made some foot pieces and mounted the boxes in them to get hight for the spraying and to move them arround.

It looks very impressive. Hope it sounds a lot better than it looks because it already looks stunning.
May I ask why you used armored glands where the cable exit the bottom enclosure, wouldn't normal compression glands worked better?

Quick update. Did some primer work on Tuesday, this time grey primer. Grey primer is a heavier primer so it fills small imperfections better. To give you example, 1L of grey primer weights 1.6kg.

Here some photos. You will see the 2 bass boxes is primer roughly, i did this just to fill all the small spots and marks. Already flat one box last night. Will take a photo tonight.

The tops was prime to and flat. Will run a layer of primer again over all the units and flat and see how the finish is and run 3de layer of primer. All in the prep work.

@Vaal to get hold of stainless compression glands is a bit of tricky one, so I went for the armored stainless glands.

I'm opp to go for the same look then the original Sasha

First layer of grey primer was flat last week and second layer of grey primer was applied. Flat again smooth and 3de layer will be added this week but this time it will be a smooth spray layer and flat with 800 paper. Upcoming Saterday is a warm day so want to check if i can do the first layer of black paint.

Crossovers is finished to.

Get a heat gun or a little heater fan and build a booth big enough from cardboard... really helps with drying time!

Fan or gun in at the bottom and a little air escape hole on top.

Thanks for the tip there Nikkel, this guys is a bit to big for this. I run the 2.2kw fan heats in the garage to help with this. You must be careful for to much heat to, because the paint start boiling or the other problem is, the object that you spraying is warm so it's expand and when it cools down it crimp again and then you get paint cracking. So if you get the surrounding temp at the rite spot, between 18C and 25C, then it will work nice.

Really good option is to get a old nice tent and build a nice spray booth but your problem is the blow over that hangs in the air and drop to the ground and that makes dust. You can build a fan option to help extract and you need to make the floor wet to keep the dust down.

Update. After I primed it last week and decided to add more primer Saturday, then i flat it with water sanding paper to get it nice and smooth.

Today i sprayed 2 layers of black with the new spray gun and really impress. Looks like 2.1bar is the sweet spot and did some small adjustments. 2 more layers to go, then red will be applied.
