When a polyurethaned floor (for example) has a small mark that needs

with 1000 grit wet&dry, and tried applying a dab of poly with a small
brush. The flaw in that approach was immediately obvious, since the
newly applied poly surface was raised and clearly not going to blend
in. I wiped it off with turps, back to the drawing board. It seems
that it might be necessary to thin the poly in order to be able to
feather the edges. If so, in what proportion, and if not, what else?

Apply the varnish with a rag or sponge?

No. Apply big blob and sand back with wet and dry once dry.. Go up to
1200 grit and T-cut.

Didnt you guys EVER touuch up cars you were selling?


I think any final step that involves sanding will produce a surface that
is noticeably different from the surrounding surface. Even a light
touch with 1000 grit is clearly visible. I haven't tried a cutting
paste (I guess that's what T-cut is.)
