Grill Block Attatchment?
 

I am in the midst of doing a front grill block.

I have everything almost cut to shape but was wondering if caulking / glue will be enough to hold the coroplast in place? I was planning to use zip ties but looked at SVOBoy's write up ( https://crxmpg.com/grillblock.html ) and it looks like he just used hot glue to hold everything in place.

I live in Maine and winter is just about here and I was thinking that the cold might take it's toll on any adhesive that I might use. I was thinking that there must be an appropriate silicon caulk out there that remains pliable in hot as well as very cold weather.

Any one have any good suggestions?

I used polyurithane calk, and it's some of the best calk/glue out there, altho it does cost about $4 a tube, it's well worth it, I've used it for all kinds of things, harshist was maybe gluing a pair of shoes back together, that held till I tossed the shoes a year latter, and at least from what I've seen you can get Black (that is what I used, with black plastic), grey, white, and clear, it tends to take 24 hours to fully set, but it will flex rather then brake the bond.

I'm sure there are a lot of ways of doing it. FWIW I took the zip tie approach, as it allows me to easily reverse the process (by simply cutting the zip ties) if/when I want to.

In my case, my grill was black, and the coorplast I ordered was also black. So all that I needed to get at the hardware store, was some extra big/long (over a foot long, and extra sturdy) black zip ties, and I had everything I needed. Then attaching my grill block pieces to my grill, was just a matter of neatly putting on and trimming the zip ties (after punching zip tie holes in the coorplast).

The only "clever" part of this arrangement, was to be careful which order I threaded the zip ties (which went through the coorplast, and were wrapped around the grill, for support), so that I was able to pull them tight from the front BUT still have the bumpy head of the zip tie in the BACK (hidden by the coorplast). This resulted in an attachment that was both sturdy and reasonably neat looking, with the only part of the zip ties that were "exposed" were smooth loops (not the bumpy/obvious head). And you have to look closely to see even that much, as these are black zip ties attaching black coorplast to a black grill...

Zip Ties. Then you will be "tray-fashionique" with the drifters too :

Also, as previously said, very flexible/removable as needed.

I have a question about the engine temperature difference with a front grille block. My car is a '93 Accord, and I live in Florida. Here it's hot all year except for a few weeks in our "winter" when it will average in the low '60's. I'm very cautious about what I do to my car because of its age and my inability to fix it if something breaks, but I really want to turn it into a green machine. How much of a difference will a grille block make when it comes to the engine temperature? If I leave about 1/3 of the grille open, what are the chances of it overheating? Has anyone had a problem with overheating with a grille block, and what were the circumstances?

I have a 3x4" opening in my grill, the rest is blocked off, and when it reached 100+ F here this summer I didn't notice the engine temp gauge going any higher then normal.

Thanks for the response. I'm definitely considering it now.

I'm going up to the North Maine Woods on a huntig trip tomorrow. I'll wave to you from I95.
