Dying / Staining PVC Experiments

I've got some epoxy based paint that may be a little safer to use on a PVC pressure vessel. I used it on my most recent paintball semi, and it didn't chip after a full day of woodsball. The only downsides are that it takes a full day to cure/dry, and I haven't found it in many colors

Do you mean the appliance epoxy paint (the stuff you paint toaster ovens/etc. with)? If so, it is tough stuff.

The way i see it, you are trying to dye plastic... i think any method you try is going to have the potential of weakening the PVC, I figure a product made for PVC will have a better chance of holding up than a product not made for PVC...
and penetration still isnt anywhere close to half of the width of the pvc walls, so pressure i believe will be fine unless you are running close pressures that are right at the pvc pressure rating...

Most of the PVC is left untouched and i dont think it will be a problem. Of course when I test, I will test behind the wall and i will test throughly .

I have tried epoxy based paints and though they hold up better than spray paint they still scratch.

I am also going to try to use different dyes with pvc cleaner/primer including RIT dye...

Sorry for the triple post, i was not paying attention at all..
oh well we are all given one slip up.

It really must've been a cheap brand, or you didn't apply 2 even coats. I accidentally painted a part that should've been taped, it took a wire wheel on my dremel to remove it.

with every thing I paint, I make sure to prep prep prep.. I also apply many fine coats, as far as the brand, what brand did you use? link to a product page?

Leather dye is often used to stain other things. That would certainly be worth some experimentation.

Do you think spray on truck bed liner would be worth a try?

Do clear coats do anything significant for scratch resistance?

Someone might want to try Rit dye, or perhaps an aniline dye (used by wood workers), in acetone (finger nail polish). Acetone won't be as good a solvent as THF but you can get acetone a lot easier than THF. Acetone should penetrate PVC to some extent.

You could also break open something like a permanent marker (like a Sharpie) and take the ink up in acetone.
