That bird looks like a baby hawk ? ...............But then again i kownothing about wildlife other than fairy things are considered mammals (Thanks Education!) .
I was wondering i short while ago Pete about the Brushed in Zinc primer in the seams you've done, from what i gather primer/s are pourous and trap moisture so wouldnt the seams zinc primer gather moisture and still rot ? obviously we cant fully stop cars rusting, just slow the aging process down, but wouldnt a coat of some paint or seam sealer whilst the primer is tacky be a good idea before the seams were closed ?
Still loving the project thread and learning so much despite not posting too much myself :),
Cheers,
Cliff
Zinc primer is not porous mate
Thats why its the perfect paint for the job. Why people still use red oxide is beyond me!
