Advice needed, any ideas...?

[The Z'eer]

I've made the decision that feasibly 2K isn't an option for me right now. Firstly I can't borrow a mask (and they're expensive to buy) secondly, apart from buying a compressor and gun I've no experience in using these tools and thirdly I don't have a safe area to spray safely without risking others health.

I'm toying with the idea of perhaps doing the prep work and spraying aerosol primer myself. This would be for a final application of 2K direct gloss by the local bodyshop. With this in mind can anyone give some advice on how to prepare a surface properly for good and lasting results? (I've removed all primer and paint and down to the bare surface) Also, and if this is so it will rule this option out, does the primer have to be 2K for 2K direct gloss on top?

Lastly, and this is dependent on the answer to the question above, I'm considering using aerosol cellulose. I know it has it's draw backs such as requiring regular polishing and fading with U.V. Although the car doesn't cover many miles per year, lives under a cover and regular polishing wouldn't be a problem.

are you talking about a whole car?

aerosol primer wont do the 2k top coat justice imo , not meaning to sound nasty but if you dont have the facilitys or know how maybe its best to strip the car then hand it over to the pros

x2 The first thing I would do if you presented it to me in aerosol primer would be to remove it and start again. Its too unstable as a substrate for quality paint. You may have been watching TV programmes where they aerosol primer their filler prep and the bodyshop just spray it? No that doesn't happen. The final paint finish totally reflects every stage of prep and no pro worth his salt will put his name to unknown self prep unless he is 100% confident in the previous work

That's fair comment there Steve, and I have been thinking about leaving the work to the bodyshop. Admittedly I do enjoy working on my own car and learning new skills (where possible) but maybe I would be better off seeking a professional.

I don't need to repaint the whole car, just a couple of trim pieces and the top side of two inner arches. I was very pleased with the actual finish of the 1K aerosol acrylic once wet sanded and polished. Sadly what let it down was the hardness of the paint, it was so soft (despite light coats) that it could be scratched by fingernail! This is why I wondered if 1K aerosol cellulose might be the answer, and possibly harder than the acrylic I used?

yeah thats what 1k products are like , if its the odd bit of trim then id suggest letting the bodyshop handle the whole job , maybe remove any lights or rubbers to save on labour

or theres 2k aerosols if you can get around the mask issue

Is there a fair amount of knowledge required to correctly prepare the surface? Aside from the aerosol primer used the surface was sanded accordingly and cleaned thoroughly with paint prep wipes.

post up some pics of what you want to paint and we can advise on the prep involved

Lechler epoxy 29107 is non iso and safe to spray at home I believe. You can get Gerson masks which are good for limited use of 2k, so should be fine for non iso primer.

Thanks for the info there I'll take a look at the Gerson masks.
