Paint bloom on cellulose

[crankedup]

My vintage car was treated to a cellulose respray back in 1963, the car has seen little use since. The paint is what I would describe as good condition with the exception of the bonnet top. This area is affected by a greyish bloom and some staining which can be seen in certain light conditions and angles of viewing. I have used Autoglym polish and waxed over with Extreme Nano wax but the area seems no better. All other panels are fine so can you advise best way forward to bring the paint back to its best? Thankyou.

It could be trapped mosture. Putting wax on top will seal it in there, so maybe worth using IPA or similar to remove the wax. Then pull it out into the sunshine if you get a nice hot day (that's optimistic though I guess ).

There may be other causes, but as many on here seem to dislike cellulose you might not get much response. My 1985 celly resprayed RS2000 still looks mostly good apart from storage inflicted damage in the form of the odd scratch.

Thanks oldskool, I guess IPA is nothing to do with the excellent beer, more to do with stripping off the wax coat then. I shall give it a go.
Why dislike cellulose?

[OldSkoolRS]

Basically cellulose is 'old school' and new paints are more durable and easier to apply (read quicker especially in drying/hardening times). It also is very high in VOCs so not very 'green' unlike the modern water based paints. I've sprayed around 20 cars over the years with cellulose, so it's all I know, but haven't done any for over 10 years and things have changed since then I guess.

IPA whilst a pleasant beer is also used in preping cars:

Not bought from her myself, so just an example.

EDIT: Just to say that this is more a theory, so I hope it works out.

Ask you local bodyshop or valeter/detailer to hit it with the polishing mop,it may well be all it needs
