shadowboxer 0 Posted March 9, 2009 Report Share Posted March 9, 2009 (edited) So I had a S12 build party yesterday and our first conversion of the S12 went great. We refinished the unit as required with Moly Resin: Blasted Wiped down with MEK Preheat to 150 Paint light coats (tried to keep parts warm) Baked at 300 for 1 hour My questions: When I oiled it last night I noticed some pigment get on the rag - a fair amount. Is this normal? There are two places I'd like to touch up - can I clean with MEK then simply respray and bake? Thanks! Edited March 9, 2009 by Shadowboxer Quote Link to post Share on other sites
shadowboxer 0 Posted March 9, 2009 Author Report Share Posted March 9, 2009 (edited) OK - update; After taking Mpro 7 to the finish almost no paint pigment came off. Also, I accidentally scratched a small part of the receiver with a screwdriver when it slipped and it scraped the Moly off. Is that normal or did it not cure hard enough? Thanks guys!

TonyRumore 1,332 Posted March 10, 2009 Report Share Posted March 10, 2009 If the finish is coming off, there was most likely a problem with your blasting operation. If you blasted the gun with glass beads, that won't work worth a fuck. The finish won't stick, and you'll have to start over. You need to blast it with aluminum oxide.

shadowboxer 0 Posted March 10, 2009 Author Report Share Posted March 10, 2009 Thanks Tony. I used aluminum oxide. The finish on my second wipe down it seems the finish is NOT coming off. Can I apply another coat and rebake for added protection? If the finish is coming off, there was most likely a problem with your blasting operation.

6500rpm 670 Posted March 10, 2009 Report Share Posted March 10, 2009 If your MolyResin is cured properly, EVEN MEK shouldn't effect it. Before curing-yes, after fully cured it's tough as nails. Maybe the loose stuff was dry overspray? You should be able to re-spray after removing any oil residue. Quote Link to post Share on other sites

TonyRumore 1,332 Posted March 10, 2009 Report Share Posted March 10, 2009 John Norrell needs to change his website on that issue. When I first got his coating, I read the directions about using aluminum oxide, but I figured, what the fuck, glass beads should work OK. Maybe not 100%, but at least good enough. Nope. Wrong. Glass bead blasting doesn't work at ALLl. Not sorta, not kinda, not good enough for a valley bitch, nothing. Moly Resin is completely fucking worthless if you shoot it over a glass bead finish. Shot over an AO blast, it's fantastic. Tony Quote Link to post Share on other sites

wadep 0 Posted March 10, 2009 Report Share Posted March 10, 2009 (edited) If you lay a parkerized base......will it matter whether it's glass or AO beads? Park over a glass bead surface still won't be rough enough. Everyone says AO is best but I blast with sand. Edited March 10, 2009 by WadeP Quote Link to post Share on other sites
Blackthorne 2 Posted March 10, 2009 Report Share Posted March 10, 2009 In addition to what's been said already, I have heard that you degrease first and then blast it. You do not want to blast first. I take it the MEK application was the de-greasing ? Quote Link to post Share on other sites
6500rpm 670 Posted March 10, 2009 Report Share Posted March 10, 2009 I degrease, blast, degrease again with MEK just before shooting finish (I hose down with MEK in a door jam style spray gun on the second degrease). If you look at this pic, the bolt carrier was polished with glass bead (smooth sheen), the gun was blasted w/ 70 grit Aulm Oxide and finished w/ Flat (SOCOM) Black MolyResin.

TonyRumore 1,332 Posted March 11, 2009 Report Share Posted March 11, 2009 I use 120 grit aluminum oxide. Tony Quote Link to post Share on other sites
