Like others, we have been trying to get back to that super smooth paint job using One Shot. Years ago when I first bought my shop, we could get it that good but not anymore...until now.
My husband took some white One Shot and added Valspar Enamel reducer 183 and then rolled some MDO. He knows to let it set a few minutes and then come back and backroll. He said that he forgot about it but did come back and roll it out. It is now quite smooth and with the next coat, should be super smooth.

I always use a sponge roller with a screw sticking in the side of the roller that prevents it from rolling. Then I "drag" the roller across the wet paint that I rolled on. Seems to work good for me.

Mr. Irish . . .I think he means to imply, in a somewhat facesious way, such labor for a glassy-smooth surface is not worthy of such a short life span . . .
However, while Oneshot might go flat within' that time under certain conditions, we don't know if Ms.Laura's sign is an interior sign, or mabey it's going to be cleared . . .or mabey it's going on the shadey side of a building or under an awning . . .
At any rate, Mr. Boone, it is not our place to assume the placement of the sign since she did'nt mention that. :x

or maybe he isn't in agreement with using valspar reducer???i was always told to use the same brands hardener or reducer...one shot makes all that. when i want a smooth glass finish i always use one shot hardener in my backgrounds. and even if i coat use reg one shot i still get a smooth finish.

Or automotive enamels..sprayed at the body shop where I trade the work for snowmobile graphics no more plywood either.... and no more failures I kinda like doin jobs just ONCE

I don't use One Shot for anything really. BUT, isn't it kind of a very expensive type of paint to use for rolling out backgrounds?

Valspar 183 is a slow acrylic enamel reducer,designed for temps in the 90 degree,it has a really really long open time,meaning its designed to keep the surface open for a long time so it doesnt skin over quick and you think its dry etc.....the longer the surface is open the longer it has to flow and dry from the surface up to the top level the better within a certain time window,so the more gloss it has. Take too long or too lfast and it doesnt have the same effect.......will the valspar 183 be significantly stronger than the one shot reducer? yes most definitely,oil based lettering enamel is nowhere near the same as an automotive acrylic enamel even though its similar,so theres more than a slight chance that reducer affected the binder to where its going to chalk later later over time,dull down,affect the tint of the color if it has to be matched later and some other things as the pigment separates away,probably after awhile ya,and no i wouldnt recommend someone do it.....if youre gonna do that just buy the auto acrylic enamel if its a solid color and roll that,toss the foam roller away and use the shortest nap mohair you can buy and you wont have any bubble dilemmas....slow one shot reducer,i dont remember the number,would do the same thing and be safer

Gavin, what about using Penetrol? I did this last summer on a few roller-blended 1-Shot backgrounds. (I almost never add anything to 1-Shot) Hey hope yer OK. Love.....Jill

I don't use Oneshot for backgrounds (mabey occasionally if it's interior only). On all exterior panels, I use industrial enamel, which I typically don't even add thinner to. I roll it out to glass by sanding the baked alum, sanding before applying the second coat, and rolling all the mini-bubbles out. I use industrial enamel only when the customer won't spring for an automotive finish.
PS: Ms.Laura still has'nt mentioned where her sign will go . . .

Sorry for not getting back...had to get hay for the my horses so that I could go to my daughters horse show this weekend and not have to worry about the my horses not having enough pasture while I am gone for 3 days.
This sign is a FOR RENT SIGN for a medical building so I can't tell you how long it will be out....might be two days or a year....just not very long term. Short enough term that hoepfuully it will not come back to bite us.

So, what paint should I use for long-term outdoor signage? I thought one-shot was the preferred paint? I do not have access to a spay booth, so I need something that will roll without the "orange peel" effect.
Color me confused

Coop, I have good luck with industrial enamels. Orange-peel seems to happen if the paint is too thick and/or tacks-up too fast. In that case you need to thin it, and don't roll right in heat, sun, etc.
Sometimes, there's just no cut-&-dried recipe. Around here, the thinning of the paint, and how it acts during rolling is often controlled by the weather that day.
I can't comment on additives (since I don't use 'em) other than mineral spirits or mid-temp reducer.
Mid-temp reducer seems to work better in most cases.
Some people use the nail-in-the-roller drag method to smooth the paint, but I tried it and did'nt like it.
Also, I'm real big on sanding between coats.
I reckon everyone has their own little gimmick that works for the end result.
