Here is the removed welting next to the NOS piece that I took off of the NOS front spoiler. Big difference after all these years. The NOS stuff is very flexible. Unfortunately the repro stuff is made only in grey and you have to paint it or dye it.

Here's how the flair looked after 5 days of soaking and scrubbing. The yellow is the primer/surfacer that I will sand off later.

Once I got it all cleaned I found a couple stress cracks in the plastic:

I pulled out the trusty plastic welder and used that to heat up and massage/melt the original material into the cracks thereby repairing the areas.

Of course things look uglier before they get prettier...

After a few minutes cooling down I sanded the area with a mini-orbital sander and 180 grit. Once that was finished, the area is just as strong as the rest of the flair:

Note to self: when you borrow one of the wife's storage tubs make sure there is not a hairline crack in the bottom that drains out 5 gallons of very expensive cleaning solvent onto work bench/old pool table which then leaks onto rug under said work bench/pool table. Because you will have to clean up the entire mess and then discover that rugs soaked in Purple Stuff overnight do an amazing job at completely sanitizing one 6'x12' area of all dirt, grease, oil, paint, etc. Now wife wants the rest of basement floor cleaned to match the bright grey rectangle.
