I'm about to spray my CJ tub with Nason Ful-Poxy then a spray in bedliner. Lots of stuff bolts in to the tub so I'm trying to decide the best way to protect the threads. It would only take about $20 to buy a bunch of sacrificial bolts but it really seems like I could just stuff bits of blue paper shop towel in there and be just fine.
Who has DIYd this before and what did you do? I've got a tap and die set so even if I bugger up the threads with primer or liner I can easily clean them out. Seems like a no brainer to me but a friends swears of I don't put the sacrificial bolts in I'll regret it. He says lube them up with cooking spray and there will be no tear out when I remove them, otherwise I'll be cutting blue paper towel out for ages.
If you're doing the firewall, make sure you tape off the studs!! When the bodyshop did my Rhino Liner, I had to bird dog them to get them to plug the holes. They used twisted up masking tape and DIDN'T remove them before it hardened. That was a mess to get out completely.
Mine was off the frame and totally stripped, so there were several threaded studs exposed on the firewall. Apparently, their logic didn't extend to the idea that if I didn't want the threaded holes plugged up, I also wouldn't want the studs coated
I used a razor knife to get the ends cleaned off, then chased the threads with a die. You can clean up the holes with a tap in the same fashion. I found that some of the holes had a lip of Rhino Liner built up around the opening that made starting bolts a challenge. I used a large drill bit to bevel away the bed liner material from the opening. Worked great.
If you have exposed studs you need to protect put a dab--that's a precise measurement--of wheel bearing grease on the threads. Bedliner might harden around it, but the grease will protect the threads. If you need to chase threads and can't get a die on the stud use a stainless steel nut. You might have to cut an X on the nut with a Dremle tool if the threads are burred on top. You can do the same thing with a SS bolt if a tap instead of a tap.
If it has electric windows and A/C it ain't a Jeep. It is a rebranded Dodge!
Just thought I'd update, tomorrow will finally be warm enough that the epoxy primer will cure properly in enough time to shoot the bedliner the same day so I prepped the jeep today. Yes, the plastic goes to the ground but I had to lift it to move the jeep back in to the garage.
