Looking forward a few months I'll be attempting to paint the shell.
Ive only ever used rattle cans so this is going to be a whole new ballgame for me.
So a question....
What size compressor will I need? I have limited space so looking at as small as I can get away with.
Do I need a fancy spray gun or is a gun a gun?
Is it necessary to "tank out" the garage with polythene or just go for it as is.

Cheers
Gaz

I can't help with the first 2 questions but It's definitely worth putting some kind or plastic sheeting, one it stops dust getting in and two stops overspray covering everything in the garage! even with it up you still find it manages to get out. I used this before https://www.screwfix...-50m-x-2m/19574 But it's too thin, easily rips. Thicker stuff it best.

 

Make sure you have enough light as well.

the one thing we've got sorted so far for ours is a moisture capture trap, our air tank has two outputs so we've fitted that on one side for the paint gun and use the other one for general use

 

quite why that's necessary I don't honestly know but my dad was reading up on it and decided we needed it

 

because the car is outside on the drive and covered with a car cover when not being worked on we've also just ordered a gazebo to build around it, which has sides we can put on to make into a spray booth or take off when making lots of sparks

What sort of paint are you planning to use?  If its 2K then you will need an air fed mask and need to be mindful of the proximity of your neighbours.

 

If its cellulose its less of a problem and just an ordinary spray painting mask would be fine (your local paint supply should be able to advise on something suitable).

Not even thought about what kind of paint yet.
Need to get all the gear together first.

The type of paint used will determine the kit needed, so the first decision is what type of paint.

2K requires an air-fed mask and other stuff. Cellulose is easier to work with, but may not give such a good and long-lasting finish.

You do need a good quality spray gun and, no, they are not all the same. the Devilbiss is an excellent choice and I've used one for over 25 years.

A good compressor with a minimum of a 50 litre tank is necessary. Yes, a moisture trap is needed except if spraying in hot & dry weather, especially if not in a very dry and warm workshop.

Spraying in what is really an 'outside tent' will be difficult in Autumn/Winter and 'bloom' in the finish can happen if the ambient temperature is too low and/or too humid. My understanding, and whilst not a professional painter, I have been painting classic cars since around 1968, is that you need an air temperature of around 20 degs C in a dry-air environment.

good point, ours won't be anywhere near ready for paint until well into next year though anyway, the plan will definitely be to do it during the warmer months if nothing else for convenience of not being wet and cold

 

we just don't have the option of indoor painting unfortunately

 

useful pointer on the gun though I might have to look those up, afaik we just have a bog standard something or other from machine mart, clarke I assume

Our shell should be ready to paint next summer with a bit of luck.
I take it the air fed masks run from the compressor?

[Midas Mk1]

I sprayed mine at home was amazed at the results. It’s all about patience.

I'm definitely doing the insides with rattle tins, if nothing else they're easier to aim into smaller spaces and the finish isn't really important (although I know they can produce amazing results in the right hands)

It does and you'll need a powerful compressor to supply enough air for a mask and the gun plus it will need to be outside your spraying environment else you'll be breathing in the paint fumes

I watch a lot of "paint society" videos on youtube (loads of information about paint sprayng) and he only ever uses a 3m double filter mask, even when he's spraying 2K clear coat with overspray everywhere.

[sonscar]

Just because he does use a mask does not make it right.It is absorbed through the skin and eyes.It only has to happen to you once.Just saying,it is ultimately your choice.Steve..

[stuart bowes]

.. and on "Car Masters: Rust to Riches" if you can drag your eyes away from the epic pair on that Constance girl, you'll notice Mark often welds without a mask on (just closing his eyes I'm guessing) but I woulnd't say that was the best policy either

[Vanman20]

Pro painters often just use a 3M type mask but they tend to spray in a booth with good extraction
