Hi all,
so my trailer has a fair amount of rust on it in sections. I used sanding/grinding discs on angle grinder to get the majority of. There are many tiny (say 1mm) pittings left. To remove these will require a LOT of grinding and material loss.
I fear for using zinc spray( cold galv) as it will blister on the pitting?
Could I use rust converter, wait a week or so for its reaction to take place, wash thoroughly and then zinc?
Otherwise some acid to remove pitting then wash and zinc?
Otherwise any suggestions please eg regular metal primer and top coat and protective film/oil?
Cheers
