Well, on my DM will this work if done correctly:
Sand down the starburst, make a silicone recess groove silicone it.
Easier said than done, huh?
If you could do it perfectly it would work. I suggest you send it to Icthus he will do cheap and really well.
But my shop is closed for now. I have way too much work to catch up on.
It’s been done before. Some people like it, some people don’t
I liked it. 
the process is tricky and if you dont have the right equipment avaliable to you it could be a massive failure, Ive done it and posted about it here:
