Q: Should I use sealant on my gaskets?
A: It is a widely-held misconception that gaskets need sealant. Manuals for most motorcycle manufacturers specify that sealant is unnecessary , but it can even be harmful. When a silicone-based or other sealant is used, it can interfere with the proper function of the engine.
Q: Which grout sealer is the best?
A: AquaMix Sealer’s Choice Gold is the best floor grout sealer if you want performance and durability. Since AquaMix is a penetrating sealer, it takes longer to apply and is a bit more expensive than topical coating sealers. However, if you do the job right, it can last up to 15 years.
Q: Does head gasket sealer actually work?
A: Here’s the bad news: Most of the time head gasket sealers don’t work . Even it if does, it’s never a permanent fix. Whether it works on your engine depends on how the head gasket failed. If your head gasket leak appeared after your engine overheated, give it up, head gasket sealer is not going to work.
