Probably been asked before but has anyone painted there own car using water based paint. Is there any precautions to take when prepping, painting, flatting out. Is it hard wearing?

Its a hard paint to spray DIY, waterbased paint is safer as it doesnt include all the iso-cyanates that are in solvent paint, but it drys differently, its sprayed differently and you will really struggle to do it without all the special equipment like a booth with air jets to dry it, (it drys by air circulation, and the air in the booth is blown around essentially but all the air is filtered for water so its dry as water based paint is as it says water based so if the water content is too high it will be the wrong mix and run.

and waterbased paint must be lacquered otherwise when it rains your paint washes off so its no less or more hard wearing than solvent based as the top coat is solvent based anyway :)

Dot bother with water based.... Pretty well described ^^ Also, it just doesn't look right on a mini, if you are doing it DIY them use cellulose but if you get it done pro then get someone who can use isosinac paint. It's only allowed to be used by registered people but looks the best. Can get a deep shine with no lacquer and straight out of the gun!

ive done a 1/4 and sill at home in my shed with water based just because i was in a rush and the bodyshop next door form work mixed it up cheap. it went on very nice, lots very thin coats seemed to be the trick. between each coat spray air gently over the area (half trigger with the spray gun) approx 10mins between coats. then blow over until touch dry then clear coat

hope this helps rob

Thats the way to spray waterbased, light frequent coats and blow it off each time, but the issue is if its not in a perfectly sealed area then you can have dust and shiz fly up into the paintwork which is a pain!

by the way artful it is Isocyanate not isosinac

Im sorry, but waterbased looks so much better, more depth and a nicer finish than celly! Agreed though, it's best left for a paint booth rather than home spraying.

[Alex_B]

Oh yes by far, if you have all the gear you can get a much better finish, its no where near as poisonous, it is much better for the environment.

but to get a finish that compares to homespraying celly, you need a very clean environment and also a lot of practice, I have done Motor vehicle body repair operations nvq Level 3 and thus also learnt how to spray and spraying water-based is a PITA solvent is a lot easier

If you are doing a resto that you want a classic shine to it, use the older paints. Agreed water based gives a 'shiner' finish but is just too lacquer shiny instead of a good depthy shine you can get from the older stuff:P

And, spray the dangerous stuff. YOLO. XD.... I will get mi coat..

im a 2pack person myself, the local factors still sells it and ive got a 150ltr 14cfm snap on compressor with a air feed mask so i can spray whatever really. but remember the clear that goes on water based is still 2 pack so a good mask is still needed

recently finnish my booth in my shed, it consits of lots of white plywood panels that screw together with lots of halogens and a big extractor and a fan that blows filtered warm air in. its abit over kill seen as i dont do much but it works very well
