OnlineJeff Posted June 27, 2014 Share Posted June 27, 2014 I've searched these forums and Google but have a quick question on a T-21 build. I'm in the final stretch on a Pandatrooper T-21 and I need to start adding bondo to the side between the PVC pipe with the ejector port and the styrene parts of the receiver. I've used some screws and e6000 to bind the PCV pipe to the wood body and e6000 for hold the Styrene to the wood. Do I need to sand and remove the e6000 that sits in this gap between these parts before I add bondo? Will the bondo stick to the e6000 residue that is on the wood parts of the body? Thanks Quote Link to comment Share on other sites More sharing options...
Bridge Posted June 27, 2014 Share Posted June 27, 2014 It will stick. Rough it up a little with sand paper to help adhesion. Doesnt need to be totally removed. Quote Link to comment Share on other sites More sharing options...
pandatrooper Posted June 28, 2014 Share Posted June 28, 2014 Make sure the E6000 does not sit higher than the height of the bondo. Quote Link to comment Share on other sites More sharing options...
OnlineJeff Posted June 30, 2014 Author Share Posted June 30, 2014 Thanks - the bondo is going well. For the ribs on the barrel, I used 1/4" rubber tubing. The primer isn't curing and is still tacky after a week. Any suggestions on what primer is good for rubber tubing? Quote Link to comment Share on other sites More sharing options...
Qikstart Posted June 30, 2014 Share Posted June 30, 2014 i would love to see an answer to this myself. I used 3/8 rubber tubing and I have the exact same issue - it's still tacky. It's still tacky MONTHS later. After my first troop to Phoenix ComicCon, I had to do quite a few touch-ups on the ribbing because primer and paint pulled off on a lot of it, but the rest of my T-21 was solid. What is the most effective way to bond the primer/paint to the rubber tubing? Trent Quote Link to comment Share on other sites More sharing options...
OnlineJeff Posted July 1, 2014 Author Share Posted July 1, 2014 I did some research yesterday and then tried Krylon Fusion which bonds with plastics and rigid vinyl (no claim to bond on flexible vinyl) - It didn't work either. I even tried cleaning the tubing with alcohol and it still didn't work. You can dye the tubing with Rit dye but it's not as dark as I need it...

trooper1 Posted July 2, 2014 Share Posted July 2, 2014 Go to an auto body paint shop in your area, and explain what you are trying to paint. They will have a mix they can make you up in a spray can. Will cost a bit more, but will work. Quote Link to comment Share on other sites More sharing options...
OnlineJeff Posted July 7, 2014 Author Share Posted July 7, 2014 @Trooper 1 - thanks for the suggestion. I took the easy way out... I'm using black 1/4" inside diameter 1/2" Outside diameter fuel line from Lowes. It was on the plumbing aisle. The writing on the site came right off with a little acetone - no sanding required. Its a satin black and I'll glue the ends together using 1/4" dowel rods cut into short sections. Quote Link to comment Share on other sites More sharing options...
