Based on favorable reviews, I am ready to apply Alclad II white aluminum to my T Bolt. I will prime with Krylon auto body sandable primer. My question. Do I need to wet sand the primer even if the surface looks ready for the Alclad? If I should wet sand, what grade of paper should I use and are there any other steps that need to be taken prior to using the Alclad?
Hmmmm, if it is a clean and smooth surface you should be able to go right to the Alclad. I prefer to use Krylon Gloss Black and there is no sanding needed with that. In fact, I just finished priming several pieces for my P-51 and am here doing this while it dries.
Oh yeah - wait 24 to 48 hours before shooting Alclad to let that primer cure all the way.
if you are using a “flat” primer then you need to sand it before using Alclad…this is to give a perfectly smooth surface as well as to reduce the porous nature of the flat paint which can leave a grainy effect on the Alclad
Try to have a look at Alclad’s homepage thay have a guide for aplication of Alclad II lacquers http://www.alclad2.com/index2.html
I have taken the liberty to copy the text from their home page. Enjoy it.
