Does anyone have trouble with paint fumes lingering using the mold resistant paints?
I may paint the inside of my Boler (haven't decided yet, as the original Ensolite is in good shape; I'd just prefer a whiter color), but I probably won't use a paint with mildewicide built in. That's not so much because of odor, but because there are some potential concerns with mildewicides used indoors in terms of their effect on one's respiratory system.
Let me stress that this is just a personal choice of mine, and that they may perfectly well be fine, so I'm not saying that anyone who has used a mildewicide indoors has made a mistake. It's just something to consider. All paints fall
somewhere on a line that runs from perfectly safe to toxic, and so with any coating you have to make a choice based on your own personal criteria.
From my background on boats I know that I can keep mildew at bay with reasonable ventilation (mildew likes a combination of moisture and still air), so I will provide that. Also, my particular trailer shows no signs of mildew at this point in its life (perhaps attributable to the opposing, small jalousie windows
over the stove and in the door, which the previous owners had a note to leave "cracked" when the trailer was in storage; I do leave them ajar most of the time as well).
For preparation of gelcoated fiberglass (i.e. the glossy side that was up against the mold when fabricated - such as the surface of the closet and kitchen cabinets that faces the living area), one should technically wipe with a solvent such as Interlux Solvent Wash 202 before any sanding or scuffing. This is to remove any mold-release wax (which, somewhat unbelievably, can linger 40 years later...) that could interfere with good paint adhesion. Once that's done you can lightly sand the surface (oftentimes the paint you are going to use will suggest a grit level to use), then wipe down one more time before painting.
By the way, it is possible to skip the mold-release-wax removal step and still get a good paint job - but you won't know for sure whether a prior owner has done this or not.
I've been wanting to try the new "hotdog" rollers but haven't as of yet.
