We just bought our first gallon. Do we need to use a regular primer over this? We are using the clear version.

Peel stop is a bonding/bridging primer and doesn't have much hiding or blocking capabilities. If you're going over raw wood, it's best to prime after using peel stop.

Since peel stop dries to a slight sheen, it's possible for them to flash through top-coat, depending upon the quality & sheen of topcoat you use.

I've went back & forth with these kinds of products, since they add an extra step before priming, and there's little guarantee offered in the event they fail. Don't consider it a primer, just the step before priming IMO.

I've been thinking about this lately. What's does a Peel Stop, Peel Bond/Trim Magic failure look like?



Instead of cracking and flaking like paint, does it bubble up and then peel off in elastic sheets?



I know the days are coming when these applications become so old I will be coming across them on repaints, rather than simply applying them on repaints.



What does the reckoning look like?

Good question. Since most substrates requiring these products already posses signs of failure, it would be very difficult in the future to pin-down a precise cause for said failure. Therein lies the genius, (for the manufacturers). I liken it to big box elastomeric on troublesome decks.

Well then that would make me an idiot for using it so many times.



Run, CD, run. We have unwittingly found the Deckover of primers!

Not saying they don't work, just can't prove they do. Nobody can. I used a similar product last year, so I'm every bit as guilty.
