## Questions & Answers

**Q: What is the difference between the MAX and the regular?**
A: The max is a slightly different white color. Different color than spray too. Which ever you choose stick with one or you will have multiple shades of white.

**Q: What's the best roller nap quarter inch or three eights to apply this with**
A: Product is super thick compared to regular paint. Shortest to no nap the best. Takes practice to get used to products viscosity. Try to apply thick and in one coat for best results. Product will self level as well and can also apply with trowel.

**Q: Will this work on a fiberglass swimming pool ?**
A: I'm not sure how long it will last because it is not reccomended for underfoot applications

**Q: Will this work to waterproof bottom of window sills?**
A: Yes. This will work well

### ⭐⭐⭐⭐⭐ It works for me
*by J***N on March 19, 2025*

So I bought this for my rv leak. I have an older rv model from the 80s it has a tin roof. So i bought two buckets of this for my 27 foot rv. I will state that it only took one bucket. I will state that I put 3 layers of this paint on my rv roof and sealed it up just fine. The suggestion I will make is dont use a paint tray with it. as the paint will stick to it and youll never get the tray back once it does lol. I suggest you use a paint tray insert instead. Also i suggest you buy a larger paint roller. it will save you time. also youll need multiple layers on the roof and each layer needs to dry. those rollers will dry fast. so expect to buy at least 3 of them. I suggest getting small brushes for detailed work or nooks and crannies. All in all youll be looking at roughly 600 bucks invested in a rv roof sealing project of my sized rv.
