Whats the preferred method of applying paint to sign surfaces, i.e. PVC, Plywood, Metal etc. How may of you roll instead of spraying. Have had some success spraying but having a double sided sided can cause some problem manevering sign sides. Anyone have some tricks. Perhaps some makeshift paint booths..for dust elimination
P.S. Is sealing the edges of Celtic necessary before i paint it? Or is edgecap the ideal way?
Thanks

I use a black foam roller, strictly oil base paints, sand lightly between coats = one of primer, 2 top coats - the last one is quite wet with some Penetrol added, the final step is to hold the roller from rolling (brake it with a nail) and lightly drag the surface. The end result is almost a mirror finish. This is not the quicky method = it takes 2 or 3 days to get it done and must dry thouroughly before handling and lettering to keep the surface like glass. Dust is a problem. A two sided sign requires some extra TLC, like propping up the edges with nails angled into the bench top. I don't use any water base paints because they dry too fast to flow out.
Of course a rush job is different.

Spraying or rolling depends on what I want as end product and what I'm using ... sometimes I'll even screenprint the background. One color oil based is usually rolled, if it needs color fades, rolled then sprayed. Rolling vinyl inks (which I use a bunch of) sucks so they get sprayed or printed if possible.
Short answer - I have none.
A (trick) I use when spraying a doulbe sided is to... set up two ladders with a 4x4 between them and hang the sign ... if the sides go in posts I drill holes in the eventually hidden area to hang from... if not then screws in the sides

I like the yellow TIZ rollers. They give a smooth finish. Just go over it lightly at last to pop all the bubbles.

if you've got the right equipment, and the space for a dedicated dust-free area ("paint booth") then spraying is the nicest way. hang your pieces from the ceiling and then you can work both sides. spraying is faster, but only if you have the right space and equipment.
i used to worry about making my panels look perfect. i don't worry about that any more. once the sign is up, i cant tell if it was brushed, rolled or sprayed. so i guess that's another way of saying "it depends on how perfect you want it".
one last tip. i used to roll the stuff straight out of the can -- now i add a little bit of reducer, and it seems to flow out and gloss up better and the orange-peel effect from the foam roller isn't as pronounced. it takes an extra hour to dry to the touch, but i try to plan my day so the last thing i do is coat the panels -- that gives them all night to cure without me bumping into them.
