I'll make a note of this. DAP Dynaflex 230 (clear) is one to avoid. It doesn't actually cure clear for long before going dark grey (mouldy?). I suspect that the chemistry is deficient in mould inhibitors.

Note: We spell mold with a U in Canada.

Well.... how can one have moulded fiberglass without a little mould?

Deb & Chuck, would you be able to compare/contrast the Pro-Flex to another product, like 3M 5200? I am putting in a new tub/shower surround this summer (quite possibly a FG surround) and I want top notch sealing around the panel edges so water won't get behind them.

I've been using Proflex for a while now. Great product but as some people have mentioned, it can be a real mess to apply. This may be old news, but here is a tip that was told to me by an RV parts guy. After you apply your bead, dip your finger in a pot of dish soap. Suddenly the proflex stops sticking to your fingers.

Instead of behaving like glue, it suddenly feels like playdough. The first couple times, I pressed down pretty hard and ran my finger along the length of the bead, but that caused two problems: 1) the bead thinned behind my finger and piled up under it to a point where it sluffed off to the sides like a furrow behind a grader AND 2) too much handling can create air pockets in the bead...which you'll have to go back and fix.

So, after running your bead and then dipping your finger in the soap, gently pat the proflex down with your finger moving along, patting it down into place(you may need to refresh your soap finger from time to time). Once the proflex is exactly where you want it to be, GENTLY run your finger along the bead to smooth it, being careful not to drag extra product along with you.

You'll soon find that you want to proflex everything. Heck, I've even done my rivets with a dollop and a pat or two. Makes a pretty good water proof cap.

Anyway, hopefully this helps make applications a little easier. I'd like to mention that practice makes perfect, AND I don't have an data as to how the dish soap will affect the proflex in the long run, so please use this information at your own discretion.

Thanks for the tip, Greg!

I recently purchased a tube of Pro Flex RV sealant. I read on the tube in Step 3 under For Resuts "If necessary, tool immediately after application with soapy water or mineral spirits and a toolling device."

I guess a fnger could be considered a tooling device. I bought some v-shaped tools at the hardware store that are for applying caulking. I haven't tried them yet.

The ProFlexRV data sheet on the Geocel web site says "a solvent such as Xylol may be used as a lubricant for tooling."

Here's a link to the manufacturer's page about Pro Flex RV:
