Yes, I scraped off all the leftover tape, and then re-applied with new tape. As for the specific model number of tape to use... I'm not sure. Try to find black thin foam ones if possible. 3M works fine. Do not use tape that looks like scotch tape, because it's too thin.
Awesome, see I need people like you around! We'll our first car is going to be my friends IS350, so I'll at least get in the practice I need to do mine perfectly! I know when u pull the emblems off there is still tape behind them...did you remove all of that first and then reapply the new double sided tape? That makes the most sense in my eyes...but then again who am I? (WD40...Psssh)
Cool, glad more people are doing the DIY.. ha ha . WD40 will not be necessary. It'll only makes things really greasy and hard to clean up. What you actually need is a good blow dryer to heat up the tape underneath the emblems. Once it's hot, you can use a fishing line or floss (I used waxed floss because it's softer and won't scratch the paint) and see-saw into the emblem. Just beware that you can't get past the prongs on the sides, so you'll have to work your way around them. If you get stuck, you know you've hit a prong. Once it's semi-off, you should be able to carefully pry off the whole thing. Be careful with the "Lexus", because I almost snapped the thing in half trying to pull it off. Once you pull it off, you can keep heating the tape so it'll roll off the paint. That was actually the painful part, because some of the tape won't come off easily. Patience is key. ha ha..
When you removed the emblems what did you use...I'd say a little WD40 to soak in and get the addhesive to loosen a bit, then blue painters tape on either side and fishing line to remove? Funny you just did this, because I have been going back and forth with the idea but you sold me it looks great. Love the matte black choice too! We are getting ready to do my friends IS350, and then possibly mine afterwards. Prep is key here!
