    Paint prep: Where do I start?

    As I press on with the Austin, I am thinking more and more about how the car needs to be prepped for paint. Will I need to strip all the paint and filler back to bare metal, or do I sand out the imperfections; what should I do? Bare in mind I want to paint it in red oxide colour, so it doesn't need to be concours quailty or anything, but what is the first step I should take from where it is now? By the way, if you haven't realised I am a little thick when it comes to paint and bodywork

    If you are aiming at a basic low budget 'daily driver' type respray, you don't have to get too carried away. First degrease the existing finish with spirit wipe then lightly sand with a medium wet and dry paper 400 grade ,remove any rust on any bare metal and spot prime with spray can etch primer , you can now use a primer filler, then a light guide coat ,now flat surface with a finer grade paper and if you are happy with the primer coat spirit wipe and you are ready for your top coat.
    Cellulose paint is easier and safer if you don't paint much, 2K is nice but there are H+S issues.

    I agree with firebird except that I like to use a sealer as the first coat to stop any bad reaction between the existing paint and the new
    Money talks; unfortunately mine just says "goodbye"

    X2 The stuff you want is called Barcoat, spray it on over the existing paint once you've cleaned it and keyed it. Then just spray your primer over the top.

    Back to basics , are you looking at straightening your repair panels or just throwing a coat of paint over the whole thing regardless of dents etc ?

    You need to take the areas that you're going to fill back to bare metal. If you fill over existing paint you'll get shrinkage tide marks at the edge of the filler at least, and possible problems with the filler adhering too if the old paint doesn't have a good key.

    It might be worth taking all the old paint right off because once you start using a long block to sand the filler down, you might find the filler covers much larger areas that you anticipated.

    Thanks, that mnakes sense. Still a while to go before I will need to start on all this. There is already dings and dents in the car, as you might expect considering it's age, and there is old filler too where it has been previously restored. That coupled with the extra filler needed to smooth of the repairs I have done and I think that a majority of the body will end up with filler coverage. I might do a skim coat of filler, but then I would need to strip all that paint off too.....
