a wide oval's whole value is the reservoir; but manage the load so a 3" full of paint doesn't sheet down a vertical face. Cut off the long point; the body covers. Long steady strokes — the loaded weight sets the pressure; a wide oval shoved hard splays and ropes. Steer with the point, keep the face flat so it doesn't roll and load one edge. Expect a fuller line than any flat sash — this is a coverage-and-capacity cutter, not a fine-line brush. Tip off and keep the wet edge live — a 3" covers ground fast enough to outrun fast latex's open time.
Asked before buying
BUYER QUESTIONS, ANSWERED BEFORE YOU ORDER
Why a 3" oval angled?
To cut long, wide exterior lines in the fewest reloads while still holding a cut off the point.
LS or Fat Boy XL at 3"?
LS is the lighter, more controllable body; Fat Boy XL is the heavier maximum-capacity one.
3" or 2-1/2" (80763)?
3" for broad long runs; 2-1/2" for control.
Crisp line?
No — a flat sash cuts crisper; this trades edge for capacity.
What bristle?
Not published — match to your coating and confirm on the listing (§8).
