Great Deal! Aica FRP Waterproof Paint Jolies Coat Set

This is leftover material from a DIY FRP waterproofing project on my balcony.
I accidentally hardened a lot of the intermediate coat material (lol), but since it was for about 10-12 square meters, a lot was left over (I think I only used about 100g of hardener because I was working in the heat).
Although I gained experience from this project, I won't be using it again for a while, so I'd like to pass it on to someone who can use it.
The purchase price was around 49,000 yen, so this is a great deal, isn't it?

I purchased it on 2025/8/27 and opened and used it on 8/30. While there's no guarantee of performance, it seems that the intermediate and finishing coats can be used for about half a year even after hardening if they haven't solidified, so I think it should be fine for a while.
By the way, the remaining amounts are as follows, but please note that the weight of the containers is included, so the net amount will be slightly less.

For the performance and characteristics of each material, please refer to sites like Waterproofing Material Shop Ichiban, but the primer JU-70 did not require sanding of the existing coating, which significantly reduced time and effort and eliminated dust concerns, making it very helpful for DIY.
The intermediate coat material is a thixotropic type (impregnating primer) that resists sagging and is ideal for rooftop waterproofing and homes.
