Removing paint from PVC tubes

Trying to take the paint off my new project is stumping me

I've tried the pressure washer and now an orbital polisher with sanding pad.

Can I use nitro mors on the PVC or is this a bit extreme?

After going through all the products at b&q I've went for this stuff

It says it's ok for upvc so I hope it doesn't eat my tubes

I would not use any abrasive whatsoever. Get yourself a piece PVC patch material and slather on the chemical stripper of your choice. Leave for a few hours then wipe off. If you get any of the PVC color on a white cloth switch to a different stripper. Once you find a compatible stripper using patches of scrap PVC then apply to your boat.

Which type of paint could that be : water, enamel, acrylic, other, Try nail acetone, car paint acrylic thinner, probably will need several bottles if that works out.

Are tubes PVC or Hypalon made ?

Happy Boating

Pretty sure they are PVC tubes. Phoned for a retube yesterday and nearly fell over at the price I was told.

Away working now for 2 weeks but keep your suggestions coming.

I'll probably do a little test with all of the safer options side by side cause I've not seen much info on this for PVC tubes

Thanks but I'm going to stick with what's there. I don't think they are past saving.

They've probably been painted for a reason (i.e. the thread is showing through). So why not get as much of the paint off as you can, then re-paint in a colour of your choice?

Xylene works IMHO often better than acethone to remove stuff, but no idea how the pvc will handle it. Fairy power spray works in some aplications as a light duty paint stripper if left on for enough time, that might be worth a try?

I'll try everything that's safe to use (not nitro mors)

I've allready got a tin of black ready to go on.

The grey has literally been slapped on so black should cover all the bad bits

Well the first paint stripper test is underway. It took the whole tub to do the top of the port tube so I reckon 5 tubs would be needed to do the whole thing. I tried it different thicknesses on different areas to see how the paint reacted.

The instructions say it can be left for 24 hours so I'll monitor it and see if any paint comes off

Well after 8 hours it never really dented the paint

I washed the stripper off and the bubbles started appearing from under the rubbing strake!

Just like a scab you can't leave alone the rubbing strake was ripped off to reveal the biggest patchwork rib I've ever seen!
