Importance of priming before Duratex

#1 Post by Bruce Weldy »

Several years ago, I purchased my last two T39s from a guy in Houston who had them built by an Authorized Builder (who is not longer on the AB list and hasn't been for years).

They've worked fine, but pretty early on they started to flake pretty easily. It was instantly obvious that the builder didn't prime the cab at all and just shot a thin coat of Duratex. Here's what they look like.

I've been wanting to get 'em fixed up for a while, so I jumped in a few days ago. I really would have like to recoat them entirely, but with my current back situation - it was all I could do just to clean up the bad spots.

While the covers were off, I tightened all of the driver bolts. I used flat black paint to cover the bad spots, then a couple of coats of Duratex. They should be pretty dry now, so back in the trailer this afternoon.

We start our summer shows this Thursday, so they will look more like my old ones....the ones that have no blemishes whatsoever even though they are a few years older, but were primed first.

Anyway, here's the after pic...

Since I had to take out the OTops to get to the subs, I did a little touch up on those too...

Also be sure to use a water based primer, I coated some cabs in kiltz primer that was not water based and everything flaked.

Dealing with life, mostly.

Glad to somewhat be back, especially doing events again.

It's slowed down some over the last couple of years. Still has some spurts of activity. Some newer faces and still a few old ones like me...
