My older 2008 CRV is still running great but the pillars were very faded and I hated the look. I shopped around trying to decide what to get and came upon these. I cleaned the existing pillars on my car with rubbing alcohol and allowed them to dry. I had to work around my rain guards which was a little tricky as they are manufacturer rain guards and way too difficult/time consuming to remove. I had to cut the upper sections of the decals to shape around the rain guards but it worked out nicely. I took my time installing the decals from the bottom up to stick them on. No extra glue used. At one point, I had to pull back the decal about mid-way up to realign, and a very small section of the decal was no longer sticky. So later my husband applied a heat gun on a low setting to get it to adhere. My advice is to take your time applying the decals as you slowly peel back/off the paper backing and smooth on as you go. I used a very small plastic scraper to help smooth out any bubbles and applied gentle pressure. I did not apply the small triangular pillar decals on my back windows as those were still in good shape. I’ve taken my car through the car wash and so far all is good. I hope they remain on for a few years like stated they should.
