Painting a glass fibre bowsprit, was a windsurf mast in previous life

[simonfraser]

It's been exposed to UV for some time and the finish has gone matt with a few loose fibres.
I am not concerned about loss of strength as it is very much overbuild.

But it looks naff. So want to paint it black or possible yellow.

Two pack paint ? Need to use a primer first, or can I use just the final color, I appreciate it will need sanding in between.
But I am unlikley to need more primer in the foreseeable future.

Always best to follow the manufacturers instructions. If it says primer and undercoat you can be pretty sure the top coat is likely to not adhere well if you don't.

If you want a hard durable finish ues a two pack polyurethane such as International Perfection http://www.yachtpaint.com/gbr/diy/products/finishes/perfection.aspx

Follow the preparation and priming described in the data sheet. http://www.yachtpaint.com/MPYACMDatasheets/Perfection+eng+A4+Y+20141215.pdf.


For a decorative but less durable finish use Toplac http://www.yachtpaint.com/gbr/diy/products/finishes/toplac.aspx. Again follow the recommended preparation and priming steps described on the data sheet. http://www.yachtpaint.com/MPYACMDatasheets/Toplac+eng+A4+Y+20141215.pdf


For a chep and cheerful decorative finish sand and apply a domestic paint of your choice.

or perhaps Rustoluem All Surface paint, which is available in smallish tins and rattle cans, gloss or matt and a variety of colors from Homebase

I'm told the two pack poly actually binds the loose fibres back into the structure to a useful degree.
I've done my carbon with 2 pack varnish. No primer required.
You could prime with a coat of epoxy, sand, then coat with anything.

Acryllic aerosol paint intended for cars would probably be fine with no primer. A high build primer is useful if you want a good finish.
