hi wondering if anyone knew the best way to spray the front of my car, but only in my garage so don't have an extractor or anything, without it being a poor job looked at compressors but in other topic's people say they need to be 5hp and they cost a fortune, wondered what people thought of hvlp turbine sprayers or if anyone knew of any others way to spray.
cheers

I use a 2hp with 150 litre tank and get very good results using cellulose - even a small compressor should be able to cope with spraying a smallish area - say two wings and boot. I don't have an extractor fan but use plastic decorator sheets to line the garage (especially the floor to stop dust blowing up ) and leave the garage door up and choose a warm sunny day when its not windy ! tricky !.

I get a good finish by cutting back the new paint using cutting paste, t cut etc so put plenty of coats on, but have never sprayed metallic finish or two pack paint which needs air breathing masks etc.

remove as much trim as you can and mask off everything else - its the prep that gets good results use panel wipe to de-grease first- the actual spraying is only a small part of the process and a smallish compressor should be able to get good results. havn't used a hvlp but again, if your not doing a complete respray it should be up to the job

a small compressors very handy to have and your unlikley to get much change from £300 to pay a paint shop to do it for you, so give it a go !

hi we did mine in a marquee on the driveway turn out ok as there was no dust. i have a 3hp compressure the v-twin type kept up fine with a devilbliss gti did the whole car. you could get away with using 2-2.5hp but you would need an expansion tank.

good lick

Cheers

I use my garage and a 2Hp compressor for cellulose. I also line the garage with the walls from my marque and leave a heater on for a day prior to spraying. This gets the garage nice and warm, it also helps warm the metal a little too. (turn heater off just before spraying) I find i get good results, and like most celly paint jobs, when you have done a colour sanding after and a good polish, the results are good.

Just painted my car in the garage with a 1.5hp 25litre compresser and it coped fine. I used 2k paint which comes with a harder so doesnt matter about it been cold and if you get dust in or runs you just flat it off then compound it to a nice shiny finish.

It does matter if it is cold. should not paint 2k below around 14 deegrees it will not dry properly

Jacob, I have the same compressor you linked to. I have used it to completely respray 2 minis as well as various panels.
With a bit of practise you will find easy enough to spray the front of your car.
As others have already said you can really only spray cellulose safely with this compressor. Although you can get metallic colours mixed in cellulose it would be hard to get a good match with existing paint (unless you were respraying the whole car).

My mistake didn't literally mean freezing cold just meant it didn't need to be baked on

You can do almost anything with celly if your prep is good. They say that prep is 80% of the work....or some similar percentage. Anyway, I did mine in summer when it was optimal for spraying. The problem you may find is moisture getting into the paint from damp air.

You definitely need a moisture trap on the airline. With celly, I found the best way to flat it afterwards is to use Maguires 1500 grit finishing paper, as it doesnt disintegrate when wet, like ordinary wet-or-dry does.

Then I used Furecla G3 cutting compund, then resin polish and hey-presto!
This is my restoration below, all done in my garage using celly.

I just used a 3HP compressor with a 50L tank, and it was fine. You may find that using a HVLP (High Volume low pressure) gun will serve you better with a smaller compressor like mine, as more paint goes on the car with less expelled into the air. I have a devilbiss one, expensive but brilliant. But I think you can buy other ones cheaper and it all depends on your budget and hom much flatting of the paint you are prepared to do afterwards.

But your prep doesn't just mean what you do with the car. Ensure your garage is clean and dust free, blow dust away from the ceiling and walls using your compressor, or brush etc, wet the floor etc. Also, you need good lighting.
With lighting, do not use incandescent bulbs, as this could ignite the vapour. Floresecent strips will do the job instead.

Also, do not have your compressor in the garage while spraying, as the motor gives off sparks as it oprerates which again, could ignite the vapour with a loud bang!!!! Perhaps no one will notice if you did it tonight as its fireworks?!!
