Painting Panels

I have a few repairs to carry out on the 90, one being cut/weld bulkhead another door bottoms, a new rear door, new galvanised tub cappings and try and get rid of the corrosion on roof and rear.
I intend spaying the panels off the 90 one at a time in the garage except for bulkhead of course. I have the compressor but need a decent spay gun.

I have not done anything like this before but on a 20 year old 90 don't fancy shelling out 3k just to scratch it on a green lane??
Anyone got any pointers on this and whether its a good idea to paint the panels separately off the 90??

I’m doing a full rebuild on my 110. I didn’t want a show car at the end as I use it off-road, and for shooting on local farms. I’m painting all my panels, inside and out, myself. I bought a sealey spray gun, it was around £100, but I have recently got the hang of the setup, and can now achieve an almost glass like finish. I would look at the reviews and look for something around £70-100 for a decent amateur spray gun. You will be surprised when you strip yours down, some of the panel insides had only primer on mine. They have lasted nearly 30 years, so painting them bits can only help.

One thing I forgot, try and spray all the panels flat. Do the inside first, so when you turn it over, it doesn’t really matter if you scratch it.

Spraying flat is best but only if you have good extraction. You have a lot more surface area for dust to fall on than if panels were vertical. Ask me how I know.

Depending on the paint you use, you'll want extremely good ventilation and/or forced breathing apparatus. Otherwise, the paint will knacker your lungs and in ten years you'll be dead. Worth considering, in my opinion, though many poo poo it

As whats been said above, painting flat does help with running paint but the amount of dust left after isn't worth it. I've done spraying in a Gala tent marquee, which is a good marquee, but even then loads of dust.Wetting down helps a bit, but also adds another issue to deal with.
Next batch of spraying will be done in a positive pressure environment (plastic sheeting taped up at seams, and a fan and filter pumping air in).
Dust on the under and base coat isn't too bad as you can rub it back, but it's much harder to get away on the laqure coat.

I used a Clarke spray gun, and it does will. Not a lot of money.

And and Al203 advised, resp protection is a must.

Air fed mask if your compressor can handle it, if not the appropriate cartridge mask.

Thanks for your comments. I have the compressor, but need a spray gun, air fed mask etc. Might just go the easy/expensive route and get someone to spray it for me.

I’m using a spray gun of around £100, and a cartridge mask. It’s a 3M mask, with filters for A1 (not sure exactly what it filters), but you can’t smell/taste anything when spraying. I would guess it’s coat me around £150-160 for the spray gun and mask, and then around £200-220 on paint. That’s 3ltrs of Keswick Green, and 2 litres of gloss black. I don’t think I could have got a full respray for less than £600, and that was just masking up and painting.

Where did you spray the panels? I've only got a single garage

I just finished spraying new rear panels for my 110. Did it in the garden / left to dry in the shed, picked drier days when outside. Did the whole thing with spray cans. Primer, paint, lacquer. All from https://www.paints4u.com. Used about 2 cans of primer, 4 of colour, 2 of lac. Took my time and did lots of thin coats with the panel standing on it's end. Very happy with the results! Whole thing took a week, but was only doing 30 minutes per day.

The stripping and prepping was the harder work.
Used these...

Worked a treat, took about 2 hours to completely strip both panels.

I was given a gazebo, but when we had the storms last week, it’s killed it. Be careful with overnight temps and paint drying. I needed to use a blow heater to keep the hut warm enough for the paint to garden over night.

You can get a cheap, but decent gun for about £30. Fast Mover do a decent one for that sort of price.

For other stuff, well you will need primer, for Landy's I always use Upoxy Acid Etch, even on the steel, works well on ali, galv, steel, everything really, has a slight high build property too it and is tough as nails, simple to spray on too, very good at levelling out and sands well if needed - most of the time I hit it with this, wait for it to flash off (1 hr max usually) then hit it with 2k. You get a 2 litre kit for about £20, don't mess with tinned stuff unless you are only doing small patches, even then half the time it's a crappy acrylic based stuff which will wipe off with thinners and react with the top coat.

Then for paint just get the colour you need, go 2K all the way - if yours is a metallic then you need base and 2k lacquer.

The biggest expense will be a decent respirator - just buy it, do it right. I have a full face 3M one that is great - great for other stuff too!
