Ok, I have a couple things I'd like to ask y'all for some advice on... So, I have this new case coming ;D , and I have some plans/ideas to make it really stand out. I don't wanna gop to much into what I'm going to do...gonna try and hit ya with it when it's all done . Anyway, I was planning on using vinyl dye for the front, but I'm not sure if thats going to work. parts of the final product will contain two types of plastic (one extremely hard, maybe not so absorbant) and some sort of moldin compound (not sure what yet). I'll be attaching a largish part to the front door and then molding around the edges to create a smooth finish. So my questions are; 1) If I don't use vinyl dye, what can I do to make the plastics more receptive to the paint and get a better finish? 2) The molding compound, I was leaning towards a pollyfilla type solution, anyone have any suggestions for something I can mold (i.e. putty knife and sanding) that work well and absorb vinyl dye?
1) You can use adhesion promoter if you are really worried about the paint sticking to plastic. But, more often than not, it will work just fine if the plastic has been scuffed (Scothbrite pad) & cleaned well. 2) For the filler, plain Bondo should work fine. You could also try fiberglass, but it would be more difficult to work with IMHO. Paint will stick to either one just fine. Vinyl dye may stick to them, and it may not. I can't say for sure, as I just use "normal" (well, automotive) primer/paint/clear.
Since vinyl dye works on metal, it should work on hard plastics. Not sure about the molding compound though
/revives dead thread I have the same question. Cany you vinyl die something like bondo? I'd like to use vinyl die on my case, because of its easy application and superior strength to paint, but I also need to do some floppy drive opening stealthing with bondo. Anyone?
Man…I’m going to have to go out and get me some of this stuff you all call vinyl dye. I painted a **** load of stuff from boats to bikes, new to old and the only time I remember using anything call a dye was when I had to touch the leather int. on a ’54 gull wing. I’m not going to comment on the dye because I’ve never use it, but bmph8ter is right on. A scuffy pad and some lacquer paint will do just fine and you can always put some flex agent in the paint to make it a little more resilient to scratching. But watch the use of the flex agent, too much and you’re paint job will take forever to dry…it also has a tendency to fish eye too.
yes I believe so I have just never used vinyl dye before, I'd like to try it, I'm just not sure how well it will cover the "bondo" automotive putty
Bondo is a trade name for auto body plastic filler with micro spheres. This is a guess (cuse I never used vinyl dye) but is should be ok because you will be applying the dye to a primer finish. You can always get a can of lacquer paint and spray the primer, the sand it flat and apply the dye to the painted surface. If you really want to be safe, you can use an epoxy primer.
