Ok so I bought a lip spoiler off ebay. It is made of ABS Plastic. I first used duplicolor primer, then duplicolor radiant silver, then duplicolor clear coat. Came out great. Then i applied 3m double sided tape to the bottom, removed the backing of a middle section...put it on the car, and began to bend it to fit. The tape stuck beautifully to the car, but it was comming off on the spoiler side. I took it off to find out that the tape completely ripped the paint+primer right off the spoiler..leaving that section black. I decided to remove the rest of the tape from the spoiler and it also ripped the rest of the primer+paint off...but this is the bottom of the spoiler that you dont see so its ok. Then I used rubbing alcohol to really clean the surface...thinking that the oil from the ABS mold was the problem. Next, i used some tough sandpaper and scuffed up the bottom of the spoiler....then applied even more rubbing alcohol to really clean it.


I proceeded to try a new batch of tape...stuck it all on the spoiler, cut off the backing of a piece of the center in order to get that on the car as a start...started to bend..and noticed the tape was just comming right off the spoiler. It was stuck on the car solid as could be...but won't stick to the spoiler for ****.


I really don't know what to do. A part of me wants to get Gorilla Glue, then glue the spoiler to the tape, then the other side of the tape will stick to the car....but the problem with that is if the spoiler ever gets chipped and i want to remove it to repaint....i probably would never get the tape off the bottom because of the glue.


Can anyone share any ideas or maybe knowledge from experience? I'm really running out of ideas.

 

ok, heres your problem. before priming the spoiler you need to rough it up a bit with sand paper to make the paint stick. then paint it and gloss it up. then it will stick fine.

the reason the tape wont now stick is because its a rough surface, paint sticks to rough surfaces tape doesnt. go out side and try to put tape on cement. does it stick, no?

so what i would reccoment do you is to sand off all the paint, re apply a primer, possibly a plastic adheasive primer, then apply the color coat and then the gloss. i would also reccomend 24 hrs between each coat, something ive learned about paint is that patients is the key. then the sticky tape shouldnt have any probs sticking. just make sure you have the right placement before sticking down.

 

Couldn't you just not paint the bottom at all and leave it as the ABS plastic when you first get it, and would it stick good to that?

 

Please post pics when you're done. Im just dying to see this thing...

 

yea that would probably work. but its too late for this guy because he has already roughed the surface up.

 

well after the tape ripped the paint off of the bottom...we tried just tape to the ABS plastic...and once again it would not stick. That's why i went ahead and roughed it up.

sandman - your procedure makes a lot of sense, and after this whole ordeal thats what i was thinking of...but i just posted this to see if there was anything i could do that would not require me to strip all the paint...and redo the whole process.
