i did a red pinline on a new board. everything was good until i went to gloss it and the gloss ate a bunch of the pinline. anyway to stabilize the red pigment? would wax in the pinline resin help? i’ve sanded it off and am going to give it another try.
go to spray painters ,screen printers ,any one who works with red …its just not as stable as other colours always bleeds something chronic…someone told me why once .something to do with where red originates from ???can anyone else tell us ???regards BERT
yeah, i knew red was bad, but i’d seen this really nice looking CI in their shop, blue with a clean red pinline. i just had to try it. i’m thinking that before gloss, i’ll put a sander over it with suncure for a fast set. less time to bleed.
You partly anwsered your own question, do use wax solution and sand the pin line before you gloss, the wax will let the line flow out much better too. Also the wax will make the resin harder, less sticky and less likely to bleed. It will be much more stable and hopefully wont bleed. You need to also use as little red pigment as possible. Only enough to make it opaque. Good luck, when they are done right they look awesome.
I remember red as the worst, pigment or paint, bleeding, overspray, no fun, till you work it out. Good advice from the people above. If you can master red, the rest is easy.
yeah, thanks MKIA, i figured if i added wax i’d hit it with 320 or lighter sandpaper. the sad thing was, i’d never done a resin pinline before and it actually turned out pretty acceptable (until the gloss!). oh well, life’s a learning process i suppose.
Yes, use sanding resin and slightly more catalyst than normal (typically necessary to do this with any pigment.) Lightly wet/dry and wipe with an acetone dampened rag. Hot gloss coat or UV should help too.
the hotter resin mix raises the question, “do i pull the tape as soon as i put the resin down?” on my first try, this worked pretty well. the resin was kicking as i finished putting down the pinline. on a second run, i put down a real thin pinline, some of the resin was beginning to kick and the pinline came up with the tape. ah, the fun of trial and error!!!
As Cleanlines would say, “pull the tape when it’s like cheese”. Still soft enough for the rough edges to smooth out a bit, but no sag. Pins are tough, especially red ones, heck red tints are tough too now that you mention it. buena suerte. Tom S.
Use acrylic lacquer instead of resin. Apply with small paintbrush or spray.
no problems with acrylic lacquer and the gloss resin on top of it?
Generally no probs. Do not apply too thickly, it dries within minutes so spraying is more effective but takes more preparation. Pull tape when completely dry, remove adhesive residue (if you use a lower quality tape) with another piece of tape not styrene or acetone,as these will remove the acrylic paint and also leave minute fibres from your wiping cloth on the board surface. These then show up after glossing as imperfections in your final coat.
