For those with G35 rear splashes: what double-sided adhesive are you using? I'm guessing the 3M stuff I got isn't strong enough because a small section of it peels right off from the stress.

Any tricks to mounting them correctly? Should I heat them? I realize this isn't a part made for our cars, but some people have them mounted so perfectly.

 

I have some 3M outdoor double sided tape that is strong as hell, it was right next to regular 3m double sided adhesive tape.

I'd try the outdoor kind for sure and heat the tape up just a bit before pressing stuff together.

 

That's what I'm using right now. The stuff that's rated for 10 pounds right? It holds fine up until the corner section at the end of the guard. Is the gray molding tape from autozone stronger?

 

use the 3m double sided tape thats got the red **** you peel off.. its the strongest

 

Pics?? Curious on how these look./

 

Did you trim them?. If not that's why they fall off.

 

And, the mounting surfaces need to be squeaky clean and free from any wax or silicone.

 

Most everyone is aware of 3-M double sided mounting tape.You can buy it
at all the chain stores,Home Depot etc.Most times this tape will work in mounting
misc.body parts.However,if you want to do a pro job with pro results,use pro
stuff.I do a lot of these types of apps.The best product to use is 3-M Acrylic
Plus Attachment Tape part#06382.It looks the same as the regular 3-M tape.
The mayor difference is the tape itself is black not grey.Black is better if the edge
of the tape is close to the panel to be bonded.In addition,use 3-M Adhesion
Promoter on the surfaces before installing.The part #is,06396.The promoter comes
is pads,"pens" and a liquid.Pads are best for doing body parts.You won't find these
3-M products at the regular auto parts outlets.Paint&body supply stores handle since
guys in the trade use e'm.As mentioned in another post,a clean surface is a must.
Good idea to rough up the surface of the part to be mounted too.Its usually FGlass.
Remember to heat the mounting tape a bit with a hair dryer before pressing the
part on the panel.If its a sunny day,lay it in the sun for a minute.Another thing
that you may encounter,parts like splash guards may not be entirely flush against
the mounting surface.Test fit with the tape on/backing on.If you have an area
that is not flush,you may have to apply another layer of tape to build up the
surface.If found this to be true in some Nismo rear add-ons.The top edge has a
slight gap.As with many parts,depending on who manufacturered the part,the quality
of fit will vary.For example,I've never seen anything from AIT that fit right.Most
Shine stuff is spot on.
If you dothe job right,the part should be on there to stay.
On your splash guards,they should also have a few screws too...

 

This.

 

G35 splash guards are literally impossible to mount without trimming.

 

Here's some pics of the lift in the guard.

 

Dropped the dollars on a roll of 3M 06382. I can't believe I just spent $40 on tape.

 

did you check your local auto parts store? most of them carry the big roll like you posted and then a smaller one for $8.99. it was way more than enough for my nismo rear add ons and they are similar length.

too late now i guess tho lol

 

Yeah, I called. They only had the gray stuff in stock. I guess I'll have plenty for future use.
