I know that their has been posts about painting pvc before, but I thought what I am talking about is different. If you disagree please delete this.

so I was reading about painting pvc. Most of them say go with a plastic paint and wait a week for it to fully cure. But I was reading at this site http://www.finishing.com/180/80.shtml (about the 5th or 6th post down) that if you paint it with epoxy and then sand then paint it with what ever paint you want then another coat of epoxy. I thought that it was genius. I am very impatient and most epoxy cures with in 24 hours And it is very strong. This would be great for me. But I want to get another view on this to see if their is any flaws.

Thank you

By epoxy, I assume they mean fiberglass or carbon fiber resin/hardener. Of course you could always wrap some real fiberglass or carbon fiber weave on there. Would offer some stiffer barrels and stronger chambers.

Still it sounds doable if you want to put forth the effort.

It should work but I don't see it as saving much time. Plus it is considerably more work and much more expensive.

Two coats of epoxy takes 2 days to dry. The coat of paint takes a day to dry, so you've got three days right there.

Spray paint directly onto PVC is dry enough to be handled within 12 hours or so. The "one week to fully cure" just means you need to be gentle for a week or so. Handling and firing the gun really isn't a problem after a day or two. Just try to minimize how much you bang it into things.

If you are going to get fancy and paint a base coat then mask and paint a design, you might want to wait several days before applying the tape. If you don't then when you remove the tape you may damage the paint underneath.

a carbon fiber gun would be sweet but I don't got the money for that I might just paint then do a coat of epoxy over that so it will be stronger. thanks for the help guys.

I think this was more about getting a stronger finish as opposed to saving time. Sounds like a good idea, and it would be considerably stronger than a polyurethane clear coat, though more labour intensive and costly.
