How to? Plastic refinish, and what type of sealant.

[Zic]

Since i don't know on what sub forum, to post this. I Thought this might be a good place.
If not, mods please move it, to the correct one.

Anyhow- got a couple of questions.-Ive searched the web and came up short
So here goes.

1- When refinishing dull / faded plastics that is not scratched. You can use a heat gun, to get that fresh black back. Right?

2- Refinishing scratched plastic, there is a method of sanding the scratches, then rubbing the plastic with some chemical stuff, and the plastic will turn black again. What is that chemical?

3- I just bought some lips for my new wheels, and forgot to buy sealant. I don't wanna order something from any other country. Since i think i can get my hands on something, here in the Faroes. What kind of sealant is used, (It has to meet some requirement, i think i read that somewhere, but cant find the post) Is it alright to use some window glue. Or do i need to find something else, that meets the requirements?

4- What is the torque spec for RH ZW1, nuts and bolts? Cant find any info on that anywhere

Hopefully someone can chime in, and point me in the right directions.

Depends on the plastic and the damage. Most cases its best to use something like Krylon Fusion and just repaint it. There are plenty of good restorers out there but they dont really restore it. Just make it presentable for a few weeks or more.

Someone once said peanut butter or straight peanut oil. Never tried this but lots of dudes on a detailing forum backed it up.


I like Meguires #40 for black rubber/vinyl but again its only temp.

I also use GE windows and doors silicone ( black ) for lots of sealant jobs like headlight DIYs and others.

Thanks man, Well yeah. On my searches i heard peanut butter as well. But its only temporally, Do you know anything about, if they get heated? If it will stay black? I really don't wanna paint the plastics.

And you mention window glue, that you use it for headlights etc, ever used it on split wheels?

GE windows and doors works fine. But get the I not the II.

Never used it on wheels but I know of people that have and Im positive its found on the other side of the pond.

I have used the peanut oil for plastics and it work well, very cheap too

Just heated it up as per the heat gun method and wiped it on with a rag, clean them up good first

Yup, works fine! But you gotta be careful... better try out on a part you dont need anymore. I tried it on my M-mouldings and it works fine, but until I got the hang of it, I had one piece of the mouldings throw some bubbles at me because I heatetd it too long, haha.

Thanks guys.

Tho can anyone tell me, the torque spec for RH zw1's?

I dont know the exact specs for those wheels but most 2/3 piece wheels ive worked with only require 15 to 20lbs of tourque. I know it doesnt sound liek much but my friend hada set of oz futuras and he wasnt sure so tightened them to 40lbs and on the first long drive about 10 bolts snapped so Im assuming that 15 to 20 is pretty accurate.

As far as sealant for the wheels I usually use any silicone adhesive that you can get from an auto parts store I prefer the black as it is much stronger, the clear will work but you need to use a little bit more of it. I usually go through 2 tubes when sealing a set of wheels, half a tube per wheel. ( standard cocking gun size tube)

I hope this helps

[Zic]

That helps a lot. I was thinking of 20lbs, since i see most wheels are about there. And Sorry to hear about your friend.

And black sealer it will be.

[Zic]

Hm, this might sound kinda dumb.

But is it Lbs feet or inch? , I will take a guess that it is feet. Since 2/3, NM sounds awfully little.
And where do you apply the sealant? Around the edge of the rim, out side of the bolt holes and inside of the bolt holes?

[hinrichs]

bolt the wheels together, then put the sealant in the part between the halves of the wheel, its very simple, ive used just aluminum calk i had at work just cuz it was silver, never had a problem with my one set at all. just put a good bead around and smooth it out with your finger or something else, let dry then put another bead on top of that and smooth out

Instead of starting my own thread I figured I'd just bump this one.

I'm looking to reassemble my 3-piece wheels and need to pick up some sealant. Does anyone have the actual name of a recommended sealant I could pick up at Home Depot or Lowe's?

[Zic]

i used ended up using sealant for car windscreens. worked out fine.

Dow Corning 832 Multi surface adhesive. You wont find it at Home Depot or Lowes. You can find a bunch of local dealers on their website.

Degrease the surfaces, lay down a bead and press it down with your finger. It helps to wear a latex glove. Let it dry for 24hrs, lay down another bead over the previous once this time a little wider so it overlaps the previous one. Once again let it dry for a full day. There is nothing more frustrating then rushing to put tires and air in them only to find a bunch of leaks.


Edit. Anyone know a good product/method for filling and smoothing deep scratches in lets say a bumper skin? I plan on fixing mine and repainting it when the time comes just not sure what to use since it has to be flexible.

[kartikeya]

Several body repair products are available for plastics. Epoxies designed to fuse into ABS plastic, and remain flexible.

I've used an example from Norton, as well as 3M. The Norton stuff was neat, it came in a two-chamber caulking gun, and they mixed at the tip. I believe 3M also has a similar system, but I haven't used it. I visit to your local autobody supply shop will answer all your questions- the staff there usually have a great deal of knowledge about their products.
