spraying outdoors and after spray advice

[Jamtarts]

I can't really afford to get my car sprayed professionally at the moment, so I was going to have a go at doing it myself,

I've got a couple of bad rusty bits and my back passenger door is very bad too along with a few general dings, scratches and scrapes.  I've had experience of spraying stuff indoors (not cars) before so fairly happy with the masking and spraying.  However I'd have to spray outside, is this quite easy to do, or is it worth getting some sort of wind shield set up for spraying (I've no idea how to rig that up, maybe a beach windbreaker or something?)  or is it not too bad spraying outdoors?

The other thing I was worried about was using T-Cut on the car after it's been sprayed (months later, not immediatley), will this cut all my spray work away if I give the car a T-Cut? Is it likely to survive, bearing in mind it'll probably be aerosols I'm using.

What's a good amount of layers of primer, maincoat (it's Royal Blue Metallic) and would it need laquer?  If so how many coats?

sorry for so many questions, thanks for your help,

Dont do it. If its a large-ish area, there is no way a rattle can will be anywhere near good enough full stop. Outside, no matter how hard you try, there will be wind, and the paint will dry before its even touched the surface creating orange peel and making it look sh!te. You will also need lacquer which is thinner than the basecoat, and you will end up trying to do it closer cos the basecoat dryed, so it will end up running. You will try and wipe it off, and make it look worse, or when its dry in a couple of weeks a wet sand and polish up (seriously t-cut is sh!te!) will expose the difference between original paint and your handywork, making it look absolutely terrible. It will end up cheaper to just buy a second hand door in your colour tbh mate.

I wouldn't do it will a rattle can either. 2 pack all the way with a compressor and spray gun.

You could get a mobile paint specialist, who can do smart repairs and to keep costs down do the prep work yourself. The one I used to use repaired a dent on a door for £75, fist sized scrapes on the bumpers for about £40 each. Scratches on a penel about £75 ish.

I do all my own paint repairs now, so it's a lot cheaper. But even if you had the equipment to spray it, you would still need to buy all the sand papers, filler, rust treatment, primers, base coats and lacquer. And after it's dry, you would have to wet sand it and polish it. Mop and G3. Equipment and knowledge I guess you don't have.

I would pay someone to do it, but don't be put off if you decide to get the equipment route, it is very rewarded doing the final polish on a paint job.

thanks guys, I think I'll give it a miss then, it doesn't sound very practical.  I might try and do some prep work myself on the bad areas and keep an eye out for a car the same colour being broken for spares.  You've saved me a lot of hassle cheers
