I have used a 2K primer (2 pack) which is not porous. The grey primer is as good as a coat of gloss paint, only it’s flat…..lol. 😆 Anyway, at this rate, I’ll be lucky to even use it in primer, the amount of time I seem to be getting to spend on it. 🙁
Good luck with your MOT.[attachment=0:2dx4wwt9]Bedford.jpg[/attachment:2dx4wwt9]
