Hi Carl,
The windscreen surrounds are a tricky area. You may find when the old seals come off they have already taken some black paint off with them. The original black coating is quite fragile, and will chip and peel easily.
You've got two choices here Carl:
Option 1.
If the visible black painted trims are in good condition, be very, very careful in removing old glue. DO NOT use the acetone, as it will fetch the black coating off in a milli second
Use a small chisel gently and carefully remove any stubbon glue, Try a 1/4 " this time, dont slip. With all the will in the world you'll still take off some black paint at some point, but keep it minimal and under where the seal goes.
You can then touch up the area beneath the seal with a good quality satin/matt black paint and glue the new seals on a couple of days later when the paints fully dry. 8)
Option 2
If the windscreen trims are a chipped/faded, scratched already, nows a good time to take them off completely, the glue's the least of your worries. :lol:
Take them down to your local powder coater and get them refurbished.
Refit and then glue your nice new seals on top.
You could always do an in between and scrape the old glue off without a care in the world, rub them down with wet and dry and respray in situ with Satin Black. But it really depends on you and the quality of job/result your after.
I've got a few tips on gluing the Bugg*rs on I'll give you, but one thing at a time eh! :lol: :lol:
Good luck
Regards
