Rattle-can over primer bad in the long term?
Discussion
Picking up a 1967 california classic on saturday.
The car has been painted over in matt red oxide (I assume primer) presumably due to the californian sun.
It's going to take months and months worth of work, and though it will be garaged, I would like to protect it from Yorkshire's damp and constant drizzle.
Was thinking of masking it off and giving it a DIY rattle can session in matt black or similar.
yes it will look rubbish for now, but I'm not too concerned about that. Will this make preparing the car for a complete respray in the future more difficult/costly?

If you want to 'rattle can' it, use Bilthamber Electrox primer. It'll protect it indefinitely and won't react with anything later.
Yes, primer is porous and will hold moisture.
No, definitely don't wipe over with an oily rag! The oil will absorb into the primer and make painting at a later date even more difficult.
No, don't use rattle can satin black unless it is an acrylic based paint.
If it is just to protect, nothing beats Electrox. It is also a superb primer for the finished repair before painting. To save money, buy it in litres (or 5 litres), buy a cheap spray gun and spray it properly. It'll be cheaper, protect even more thoroughly (the paint isn't as thin) and will be good practise for you

also as I really wouldn't mind a different colour on it for now, are you saying an acrylic paint would be non-porous? is this what I should be looking for?

Electrox is a purposeful grey and very easy to apply. It is also an etch primer so it sticks well.
Acrylic paints are not porous but more pointedly, satin acrylic is not porous, unlike some other satins. Go to a paint shop supplier and get some of the larger acrylic satin aerosols if you fancy that route. They usually sell them for wheels etc.
The only problem is if you try to apply the satin black to the car as it stands, the paint won't adhere very well.
Whereabouts in Yorkshire are you?

thanks a lot for that. I'll have a think about what I need to do, and try and work out the protection, cost, practicality and effort of both solutions.Electrox is a purposeful grey and very easy to apply. It is also an etch primer so it sticks well.

As that matchmaker benjj says, we're not too far away. I sold a kayak to someone in haworth yesterday (to make room for the mustang), you wouldn't look a bit like Justin Lee Collins would you?

You're right. I wouldn't look like him.... at all!
Always loved Mustangs. I'd enjoy taking a look some time.
cheers TWAlways loved Mustangs. I'd enjoy taking a look some time.
got a long way to go before I get to that bit. Though the engine runs perfectly, the car has been sitting in a garage for 15 years so have to refresh everything before running it properly.
