This will be the third time in 4 years that our 4 year old deck needs to be restained, and the past two times I have used TWP102 with less than satisfactory results. Does anyone have suggestions on what to do instead or what to use instead?

The deck is PT and on the North of the house, in Michigan. One level is about 30" off the ground, the other about 20". Only in the area that is shaded has the TWP held up, most other areas the finish is completely gone and it looks like new though not green wood. When I stained the first time I used a mill glaze removed and oxicylic wash thinking that would open the pores of the wood; instead this stuff seems to be not allowing the stain to penetrate.

In comparison, another deck on the north side that is at least 15 years old or maybe more, just sucked up TWP and this will be the second year and the finish looks great. The wood however is very rough from continual power washing by previous owners if that tells you anything.
