patrick reif Posted February 15, 2016 Report Share Posted February 15, 2016 Home Depot has an rtv high temp silicone for car gaskets. I remember reading about someone making molds from clear silicone sealant, and figured the high temp silicone might be a better choice. Has anyone tried this yet?

FATFLATTIE Posted February 15, 2016 Report Share Posted February 15, 2016 I know nothing about this but I have read there are some kinds of silicone you should not pour in. I will let somebody smarter than me chime in on the specifics. Quote Link to comment Share on other sites More sharing options...
