Coating the inside of a turbo

[oguitar]

How do you suggest I coat the inside of a turbo? I am using TLC Colorgard Black. The turbo hotside has been ported and polished. The smooth surface and coating are not working together very well. I don't want to ruin the smooth surface. Is there any way I can get the coating to adhere with out sandblasting? Thanks for the help.

You are going to have a hard time getting any coating to stick to the polished surafce. I would recommend no coating

After three attempts I am going to agree with you. No coating it shall be.
