Greg_D Posted Saturday at 01:13 AM Report Posted Saturday at 01:13 AM What would be the best way to clean up the mess someone made with the RTV here? Does this stuff need to be scraped off or is there a solvent that will remove it?
N201MKTurbo Posted Saturday at 02:09 AM Report Posted Saturday at 02:09 AM Once you have scraped off as much as you can. Acetone will sort of take off the residual film. There are silicone cleaners out there. They are expensive. I’ve never tried them.
Schllc Posted Saturday at 02:18 AM Report Posted Saturday at 02:18 AM It does serve a purpose. what about taping off a section and battering more rtv over it to make it look intentional. may be easier than cleaning. 2

Mark89114 Posted Saturday at 12:40 PM Report Posted Saturday at 12:40 PM I assume this is silicone based, Lowe’s sells something that breaks down the bond between the silicone and the surface. Can’t remember why I have it or if it worked, nothing will break down the silicone itself.
GeeBee Posted Saturday at 12:53 PM Report Posted Saturday at 12:53 PM Ford makes a silicon remover called Motorcraft Silicon Gasket Remover, part number ZC-30A available on Amazon. It works like no other. I use it to safely remove the glass globes on my outdoor lights that are RTV'd into place. I also use it on my boat to remove deck hardware and such. It takes about 24 hours to work, but work it does. That all said, what is pictured is no worse than most. I don't spare the silicon on my engine and in cruise my cylinders run in the low 300's. Don't let "pretty" be the enemy of cylinder life. 1
Slick Nick Posted Saturday at 05:41 PM Report Posted Saturday at 05:41 PM While the main objective is to seal the baffles, I’m always amazed at how many mechanics will just gob the RTV on like that. Only takes a few minutes to run a couple pieces of masking tape before you apply the sealant. Hit it with an acid brush to make it lay down a nice texture and then remove the tape. Professional looking sealant every time. That looks awful, I don’t blame you for wanting to redo it. 1

Too thick of material.125 made from a roll Should Be .093 and cut from a sheet We die cut from a 48" wide sheet To clean use Toluene We die cut all models in seconds
