Paint peeling.

[nasir]

Hi how is everyone doing, I am thinking of painting a shell for my brand new Xray 808. But every time i paint a shell it starts to peel off and on nitro on the exhaust part and hot areas it just totally peels off. What methods do manufacturers use to paint the shells without the shells peeling off or full of duct tape :gulp: lol

Thanks

What kind of paint are you using to paint your bodies?

Regular spray paint will peel. You need either polycarbonate specific paint from you hobby store or Krylon, which I understand will adhere to the Lexan and is flexible enough not to peel off.

Thanks for the replys guys i am using Tamiya White Polycarbonate Spray

Thanks

You need to clean the inside of the body thoroughly with soap and water, then with denatured alcohol before painting it.
The body contains a release agent that will keep the paint from sticking to the lexan.

Rolex not trying to sound like a know it all but thats the krylon fusion paint for plastic. Going back a quite a few years what we use to use before lexan paint was around,was automotive vinyl interior paint yes they came out with the bodies before they thought of color! I would deffenitly stick with polycarbonate specific paint.(prep is everything)

The krylon fusion may stick for a bit, but it won't last. I've tried it on motorcycle plastics before.

More like a few decades ago. LOL

I was using Tamiya paint for polycarbonate back in the early 80's. Kyosho had their own line of paints as well back then.

To help with the heat coming off the pipe and header, I used to stick a couple of layers of aluminum tape to the inside of the body at the hot zones. It is very flexible so it easily forms to the contours of the body. You can get it at pretty much any home improvement store.

Yes i agree with you the right paint is the only way to go!

Krylon fusion will not hold up on a lexan body. The ONLY non lexan specific paint I will use on a body is Krylon ultra flat. I have used it in several colors, mainly flat black, the flat black adheres extremely well to lexan. I have used it on a number of bodies and it holds up very well. Plus, if you go for the flat black look by painting on the outside of the body, when it starts to look crappy just remask it and shoot a fresh coat of black. But I would recommend against using any other paint not specified for use on lexan polycarbonite bodies.

The prep is just as important as the paint, you must wash it well with soap and water, then a good wipe down with da.

Another good idea during the prep is to use a green scratch pad to rough up the body where you paint before you wash it. This will give the surface a bit of "tooth" that the paint will adhere to better.

Just do not scuff the windows, or anywhere you plan to use chrome paint.

 

[hamz9561]

I usually do it right after I ask mask the windows. I didn't think to add that.
