Repairs to chips on white mast?

[Tim Good]

I have a nice one piece 18m proctor mast. Since bought by Selden. However it's slowly developing chips from 22 years of service. What advice would you have for repairing such cosmetic blotches? Ideally not taking it down and having it entirely redone.

Thanks... have you used hammerite spray also? If not would you paint and then polish back to smooth?

Some paints are incompatible with some primers, I'm told. And there are many different 'white' paints....

One could do worse than ask these people https://www.andrewscoatings.co.uk/ who have significant expertise - just look at their website - and at least one of their specialist advisers is a yottie, too.

Just used hammerite smooth brushed on. Ive found out that it is relatively "inert" ie doesnt react with other stuff. If you wanted to be supersure use hammerite primer on top of the etch primer. The etch primer is essential due to the aluminium

That blistering is corrosion underneath the paint. That all needs to be cleaned back to bare metal as mentioned above but aluminium corrosion needs to be neutralized with Deoxidine-624 before the etch prime goes on.

Good to know thanks!
