hey guys. i was thinking of painting my engine cover, but i think the texture will come thru and make the paint look bad. im pretty decent with body filler, but im not sure the bondo can handle the heat. what do you guys think?

thanks alot!!

Huh? I'm confused. Can you post a pic of the cover?

i think he is saying he wants to put a glaze coat over the textured plastic to cover the texture. i would be more worried about it not adhering just because stuff doesnt stick to plastic very well. i have painted stuff with just the krylon plastic paint and that worked pretty good

I think you should remove the engine cover and let your engine breathe. If you are going to paint it, skip the bondo. The texture will be reduced by the paint, but some of it will still show through. What is the problem with that?

Ok, if he'* painting it, then why not do some light sanding to remove the texture? Then paint it? Or, just put a heavy coat of primer on. Make sure you use primer specifically for plastic. Its a different bonding agent.

I think either of those options are better than bondo.

The short versoin: If you want to paint plastic, flame the surface with a propane torch first.

The long version: Most plastic appearance (non-structural) parts in a car are either made from polypropylene (PP) or thermo plastic olefin (TPO). The main difference between PP and TPO is TPO has a higher rubber content. Both are olefin based resins, and when molded will leave a film of pariffin (wax) on the surface, which is why paint won't stick. TPO is generally more paintable than PP (bumper fascias for example). One sure way to improve paint bonding on PP or TPO is to "flame" the surface to be painted. Take a propane torch and pass it across the surface. Obviously you have to be careful to not hold it too close, or too long, at any one spot or you will melt the surface, but flaming will burn off the pariffin film and give you a better bond to paint

thanks for the tip, roy!. i just need a small winter project and i like to make it look super smooth. as of now, i have a colormatched fob, and a colormatched xbox controller. on a side note, that rustoleum paint for plastic coupled with rustoleum plastic clear is no joke. my clicker still looks like new, and the xbox remote has hundreds of hours on the paintjob with no ill effects!

I am just confused why u got a remote for the hood ornament LOL..
You are not thinking of attaching it there are you? ha ha..
It looks kinda cool sitting & color matched on hood there..hmmm..
Nice paint work..I need to do my FOB..good idea!

its a remote for the car so he can sit in the back and freak people out

Ya And if The remote does not work ....
I can see him using Bondo on his next project!!!
