: Doug,

: MEK works better than Acetone to remove the light film present on PVC . It
: dulls the surface, and removes a little of the vinyl in the process.
: This "etching" creates a stronger bond between the PVC (vinyl) and
: the vinyl
: cement.

: I have found that a kitchen paper towel works well for applying MEK.
: Just wipe it on and allow to dry completely. If the surface still looks
: glossy, apply again. Avoid "pooling" of the liquid as that can eat
: through
: the vinyl. ( See attached pic)

: Surface moisture is a by product of MEK, so be sure the surface dries
: completely before applying vinyl cement. A heat gun is an excellent way to
: speed up the drying process. If MEK is unavailable, as is the case in some
: countries, acetone can be used, but it is less effective in my opinion. I
: purchase MEK at Lowe's or Home Depot, and many other hardware stores.

: MEK + P ( peroxide) is the catalyst for polyester resin.

Wow, a gallon can, you're brave

I've got a quart around here somewhere, but it stays in the garage and if I could would stay outside. Stuff borders on explosive.
