They are foam so there is nothing to shed, but they Blow-Up and get mussy. You shouldn't have time to dip the brush. 2 swipes with the roller then tip. All in the time it took you to read this post. The roller is in your left hand and the brush is in your right. The paint is pushed along with your feet, or get a friend to hold it. If the brush starts to build up paint wipe it on your shirt. Keep moving, don't go back.

I never had one shed. They will get soft and start to expand after about 20-30 min., but I never had one fall apart in that short a time. Check to see if you bought the one for this type of paint.

I meant to say they last about 15 minutes, then start coming apart. The good thing about 545 is that is sands easy and does not seem to leave marks where the nib was. I ordered some hot dogs from an awlgrip distributor in Fl.

I top coated part of the boat yesterday. I thinned 33%, used a hot dog. The brush seemed to leave a less smooth surface than just the hot dog. So I just did the hot dog. The brush was not a high quality brush, which I have on the way. Since I am going 4-5 coats I should be ok, just need to get the last one.

Good news is that runs were very limited. I am happy with the result. Interesting that the hot dog did not come apart using top coat like it did with the 545.

Back the thinner off to bout 30% or a tad lower for second coat or same recipe? BTW, its was near 100deg, and will be for the next week.

545 has stronger "reaction",,it'll eat things way before top coat does,,
and since your doing top coat,,,even tho you sand between coats,,,im pretty sure you still wanna be VERY careful with the "looks" of your bottom coats,,,,,but as usual,,,i aint sure,,,,,kapt. will be tho,,,hehe
and Happy ta hear its going better fer ya

Much is right. You will have to sand between coats. Each coat needs to be smooth, maybe not with the gloss you are looking for, or the color depth, but as smooth as a babies ass! You shouldn't be getting a good finish with just the roller. If your mix is thin enough you should be seeing LOTS of air bubbles. That is what you need to tip out. Don't be too concerned if your brush leaves a few ridges when you first tip. They should flow smooth in 5 or 10 min.

Repeat of yesterday, results about the same. Stuff goes on and stays in place more less. New brushes arrived today so I can give them a go tomorrow. It just seemed the stuff was too thin to brush. That is why I asked about dropping reducer to just under 30%. I am at 1/3, or 33%.

Its also 95 deg out instead of 65 as before.

The distrubtor sent me 2 brushes. Corona Urethaner china bristle brush. And Corona Europa badger hair brush.

I am sanding w/ palm sander and 220 tween coats.

wait fer kapt.,,,but this is my take,,( we'll see if he taught me anything),,i think i say sand with 320,,,so he'll say sand between coats with 325,,,,then he'll say,,,,,the brush isnt suppose to hold the thin paint,,,,its for evening out your roller marks and to take the air bubbles out that the roller caused,,,,,,,,maybe,,hehe

What I saw with the lower quality brush (brand new - dry) is the drag marks were not going away as if there was not enough paint there to flow out.

Jim has been paying attention!!!

Right, You don't paint with the brush -- as light as passable you smooth out the roller marks. One very light stroke. That's all. Use the badger. The pros use 220 because it saves time. You are working for yourself, use 320 you will get a better final.

Good result tonight guys, 2 hours 40 min R&T, did the whole interior 26 Mako WA. I used the urethaner and it seemed to be laying it down nice. I guess the guy meant for me to use the badger for last coat? It was slow swtiching back and forth. The hard part is the cabin, the gunnels for the walk round, skinny working and lots of deep bending. Ugh. Back screaming at me.

So frigggen hot I cannot wear gloves. The gloves trap the sweat, grab a rail for support and a puddle shoots out on my work.

Hearing you in my ear while working, tx.
