White specs in gloss when painting composite door

[Dougie212]

Hey there

A pal of mine is currently painting his composite door and is having a bit of a nightmare.

He’s sanded the door down, washed it down with sugar soap, primed (using exterior wood and metal primer from wilko), wet and dry sanded, primed again, wet and dry sanded again. Put one coat of gloss on using a roller and has got small white spots over the door where it almost looks like the paint is being rejected from that spot. They’re pin head sized but all over the door. I’ll upload some pictures when I get them.. but in the mean time does anyone have any ideas why this is happening? I would have said it’s contaminants or grease spots on the door but he’s sugar soaped, rinsed and let the door dry…
Any suggestions would be hugely appreciated.
Thanks
Dougie

Fish eye in paint maybe? Look it up

Thanks Wayners. Any idea the best way to tackle it? Online seems to show a lot of car spraying solutions but nothing for painting and gloss.

I agree that the look like fisheyes.

The good news is that they will not occur anywhere else on the door.

I would bush paint on to each of the fisheyes and leave it for a few mins. If the fisheye reoccurs, wait until the paint thinkens slightly, then run the brush over it again. I assume that the paints used are water based. WB paints can be quite fussy in those kind of circumstances, but wiating until the paint thickens slightly often helps.
