Here is a very interesting product to help with Level-5 finishes.
Or Level-4 for that matter.
It's not clear like Gardz or Corotech® Clear Acrylic Sealer V027, it's white.
So it's very easy to spot imperfections in drywall.
I wonder if any members here used it and how it performed for them.
Maybe there was a thread or posts about it and I missed it.
Maybe this primer is better than the primers/sealers from paint stores.
I'm going to try it for sure.
The only reason I would apply clear sealer (like V0-27) on top of FIRST COAT PRIMER, is to gain the extended open time (especially when painting on hot dry day), clear sealer will also add to the sheen uniformity as well.
From description of this product, it sounds like it could be better primer than most of the paint store primers, (perhaps even including BM Fresh Start).

Here is some info on it:
Addresses drywall decorating problems by minimizing surface texture variations
• Minimizes joint banding and photographing
• Dries to a white finish in under 30 minutes
• Designed for fast, economical application
• Applies with brush, roller, airless or conventional spray
Decorating problems (commonly referred to by such names as “joint banding” or “photographing”) are usually caused by differences between the porosities and surface textures of gypsum panel face paper or concrete and the finished joint compound, and are magnified by the use of gloss paints.
When viewed in direct, natural lighting under these conditions, the joints and fasteners in decorated walls and ceilings may be visible.
Unlike traditional primer/sealer products, USG Sheetrock® Brand First Coat™ Primer has been formulated specifically to equalize both porosity and surface texture differences and provide greater uniformity of the finish coat.
In contrast to a sealer, USG Sheetrock® Brand First Coat™ Primer does not provide a film that seals the substrate surface.
Instead, it minimizes porosity differences by providing a base that equalizes the absorption rate variations between the drywall face paper and the
finished joint compound when painted.
USG Sheetrock® Brand First Coat™ Primer also provides the
proper type and amount of pigments and fillers (lacking in many conventional primers and sealers) to equalize surface texture differences.
This product is not intended as a final coating—it should be overpainted when dry.
This versatile primer can be intermixed with wall and ceiling spray textures to
enhance hardness, bond and whiteness. Surface priming recommendations on texture bag still apply.
1. Allow USG Sheetrock® Brand First Coat™ Primer to dry and then apply a quality wall size before applying wallpaper or vinyl wallcovering.
