色々 撥水コーティング剤 使ってきましたが最初はいいですがワーパーが泣いたり、撥水効果が薄れたりで、効果3カ月~半年 などと書かれていてもとてもそれだけはもちが無かったりしましたが、これは撥水効果も文句なしでシャンプー洗車しても効果は変わりなかったです。ただ 付属のスポンジは液を多く吸ってしまいうまいこと塗れませんでした。直接ガラスに液をたらし紙クロスで伸ばして使ってます。これがなければ★5個。 製品的には満足してます。もう少し安ければ大変満足。

【使いやすさ】ムラなく塗って拭くだけなので簡単 【ふき取り】乾いたらティッシュで拭き上げマイクロファイバークロスを水で絞って仕上げ拭きするのでこれも仕上がりは綺麗です。 【コーティング効果】時速35km位から水滴が流れ始め、時速50kmだと雨がしたからウインドウを駆け上がっていきます。 【内容量】調子に乗ってミニバンの全面ガラスに塗布しましたがまだ余っています。 【持続性】これだけはこれから判定します。 【価格満足度】 【その他】

ガラコは、ウロコ状のあとが残るので大昔から使っていません。そのころから、愛用していたコーティング剤を買い溜めして20年ぐらいしていて同じタイプらしきものをPIAAのブランド名で買って、次も…と買おうかと思ったら買えずやっと同じタイプのコーティング剤を見つけました。 まだ購入したものは使用していませんが、値段が以前のよりも2~3倍は高いので、値段見合う性能を期待したいところです。 今度は商品が無くならないことを希望します。
