Aeruk Posted February 18, 2013 Share Posted February 18, 2013 I'm having some issues with a few resin pieces. I washed these with warm water and dishwashing soap, primed and painted flat black. I'm getting strange surface problems and these small dimples, and no amount of sanding and recoating is making any difference. Did I need to scrub them more before priming? If that's the case, what can I do now? Is there a good way to strip all the paint off of these guys safely and start over? Any help from the pros would be greatly appreciated. Thanks!

chilledmilk Posted February 18, 2013 Share Posted February 18, 2013 to remove the paint on the parts you can try soaking them in a bath of simplegreen over night, if the resin is remotely similar to GW models it shouldn't hurt the pieces at all. those look like air bubbles in the mold. after stripping you can always sand down the bad areas and use either a small amount of bondo just to smooth over or "green stuff" its a modeling trick people use to fill in little imperfections. should work the same. (but im no expert when it comes to w/e that was cast in" links below to what green stuff is http://www.games-workshop.com/gws/catalog/productDetail.jsp?prodId=prod1380024a&_requestid=196374 http://www.loctiteproducts.com/p/13/6/epxy_putty/overview/Loctite-Repair-Putty-Multi-Purpose.htm Quote Link to comment Share on other sites More sharing options...
Chex Posted February 18, 2013 Share Posted February 18, 2013 Yeah that's not from the paint, it's from the parts themselves. Easier trick, go to your local autozone and get a small tube of Bondo spot filler. Sand the areas with some high grit sand paper (400 or 600 grit) and take the paint off. Spot fill, sand smooth, and then repaint. Remember when painting though you should spray light coats to get the desired color. Don't just go heavy black all at once.

Aeruk Posted February 18, 2013 Author Share Posted February 18, 2013 I'll try sanding, filling, and sanding again. The bubbles weren't visible before I started painting. Even if they were there, though, it doesn't explain the strange surface sheen I'm getting around that area as well. Maybe the bondo will help with that too. Thanks for the help!

TB5994 Posted February 18, 2013 Share Posted February 18, 2013 you could always try filler primer, as its thicker than normal primer, it should stop the resin absorbing the paint, which is what it looks like, the resin is sucking the paint in like a sink hole...

NegativeEleven Posted February 19, 2013 Share Posted February 19, 2013 I have that issue sometimes with metallic spray paint (usually Krylon Aluminum). It happens if I start spraying right on the piece, what comes out of the can first is propellant. It leaves a slick spot that paint won't stick to. I end up having to sand that spot again. I always try to remember to spray a little off the piece, on newspaper or cardboard till the actual paint starts coming out of the can. Of course, I get in a rush and forget, probably 1 in 10 times.

Aeruk Posted February 20, 2013 Author Share Posted February 20, 2013 Thanks for all the advice. After sanding the affected pieces, I tried the filler primer. It worked fantastically on all but one of the t-bit pieces, which for some reason was still soaking it up. I resanded that one, patched it with bondo, and reprimed...seems to be okay now. The second coat of black is drying on them now, and they're looking a lot better. Quote Link to comment Share on other sites More sharing options...
Griffin-X Posted February 21, 2013 Share Posted February 21, 2013 All good options posted above. In my experience, the sanding can actually open up more pores and create even more problems, as you've seen. Different types of resins cause different reactions to friction. Also, the resin may not have fully cured or remained porous. The bondo trick usually works well since it seals it up nicely. Glad it all worked out.

NegativeEleven Posted March 15, 2013 Share Posted March 15, 2013 I meant to get back to this thread. The resin I have been using to cast blasters is doing exactly that. It's like the material is repelling paint in certain spots. It's very similar to what I said about metallic paints shooting more of the propellant than paint, but that can be sanded off. This problem doesn't seem to sand away, so my other option is coating the whole thing in bondo before painting it at all. I'm gonna head out and look for that filler primer. Is that at auto-parts stores? Quote Link to comment Share on other sites More sharing options...
Aeruk Posted March 19, 2013 Author Share Posted March 19, 2013 I found it at Menards (a regional hardware/home improvement store chain). They have a rather large selection of Rustoleum spray paints. I'm sure you can find at a comparable store. I've bought paints at Home Depot as well, but my local one doesn't have nearly as large a selection as Menards. Here is what I bought, and it worked great: http://www.rustoleum.com/CBGProduct.asp?pid=11 Quote Link to comment Share on other sites More sharing options...
