Aluminum sealer?

[jucasan]

Hi,
Just finished my first aluminum frame and I was wondering if there is a sealer or something to cover small porosity prior to power coating. Any suggestion?
Thanks.

Ask whoever is powder coating your frame........

Given the nature of powder coat, the small voids will fill, I agree, ask the technician prior to applying the finish
