Re: Repost: (cheap and good) coating tool

Hi:

Thanks Ryuji.

The paint/finishing pad I use to finish the coat is one of these. I can
get nice 7 inch wide ones with a nice handle. I tried coating my size
with just these, but found I didn't get an even coverage, but that may
have been with some of the thicker sizing mixtures I experimented with.

Doing bad sciene - introducing way too many variables at once :)

The rollers I have been using have essentially the same surface as these
paint/finishing pads, they are simply round roller version of a finishing
pad.

I've been using finishing pads when coating gum - I brush on the gum mix,
or roll on the gum, and finish the coat with a pad - evens everything out.
I've been able to get nicely coated gums this way.

Considering adding some tween 20 to my gum mix to reduce the foam and
bubbles the roller introduces. Has anyone done this?
