Worried about a couple of code 55 issues

Hello all,

After many struggles laying track I finally completed my main oval. When I started doing some tests I came across two worrying issues:

1) 1mm gaps in some insulated joins. Probably due to a combination of poor filling of the rail profile, the track shifting while placing nails or even movement caused by curved pieces of track that cause tension on the adjacent sections.
2) On some places I had to cut a bit of plastic from the turnouts to have enough space for a turnout connected to a double-slip. This required cutting a piece of the motor (PL-10xx) support area and also a bit of the tie bar. This of course compromised the turnout for future use.



So with these things making me question everything I would like to ask your opinion:

1) Is there anything that can be done to fill the gap on the insulation joiners? Or should I redo the whole thing?
2) Do people usually have to irreversibly cut expensive items like a turnout ? Or is there a non-destructive way of creating this particular combination ? (turnout after slip/crossing)

Thank you
