When you say wire brush, were you doing it by hand? Nothing comes off if I do that now I find. The angle grinder with cup brush is effective but hard on the hull and impossible to contain the dust.
What were you using for grinding? I have a random orbital with 80 grit that does ok in terms of dust, but is incredibly slow and didn't get into corners well. What pressure were you using, in lockers I only seemed to get loose flakes off.
I'm trying to decide between a tsp bleach mix or a commercial paint prep(mostly sodium hydroxide). I love simple green(the industrial stuff, crystal simple green, not the residential multi surface cleaner)
Trying to figure out the order, should I pressure wash now and then sand again if needed, or finish all sanding etc first.
Re: eggshell vs semi gloss. having painted quite a few houses, I'm just cautious about it as semi gloss really did show defects that eggshell hides. I don't mind painting, I'll be doing it again in 5 years if I still own the boat anyways, to keep up mold resistance and fix scratches etc. it's the flaking, and other failure that worry me. Taking it all off sucks, a light sand and top coat takes a few days at worst. Is the failure of eggshell more likely to be a grind back to hull again exercise, or just that the surface gets shiny if scrubbed too hard?
Hull will be fully insulated, insulation glued down but I think I'll go buy some mold resistant primer as you suggest tardis. If I didn't already have my foam ordered,(half inch volara) I'd switch to armaflex. Not a big fan of reflectix unless temporary or other requirements involved. I can say that the only non molded places were behind taped down reflectix but I prefer the look of a nice foam. For v berth I'll be going with a light mold resistant carpet over top in areas that a sleeper might roll against.
Would like to try the new laminated volara some day, one side is hdpe(like the thin flexible cutting boards) which should be great in lockers. Minimum order is too big for me though.
I've got a sample but I'm trying to get them to send me enough for one small area, I want to see how it wears and if it can be resurfaced, could be amazing if so.
