Boedeker Plastics : How to Identify Plastic Materials Using The Burn Test

You can identify plastics with a simple burn test (scrape a bit off the edge) or with solvent tests. If you get some scrap from a local plastics house, you'll have something to compare yours to, and that will make it easier to identify.

WE use Silpruf...as it retains the most flexibility. Its adhesion to teak...should be fine...but check.

Looked at my boat today, it appears as tho the caulking for lack of better term that is on the top of the lexon is worn out or equal, and letting water in at the top. Did this 5 yrs ago, so will have to do it again I guess. Then again, along with this bead redoing, may pull the thru screws an re caulk too. This takes to people vs one.

Will check out Atlas supply to, Hopefully they have a clear for the bolts, and black for the upper and around the window part.

Thumbs up

We rebedded four lexan (c) large fixed-port lenses in '95 with LifeSeal. Still never a leak.
It just works.
Note though... that are some simple tricks of the trade to get a permanent seal with the more-thermally-active Lexan.
