When applying Flex Seal on an airboat, the number of coats required can depend on several factors including the material of the boat and the extent of protection needed. Typically, for a standard application, it is recommended to apply at least 2-3 coats of Flex Seal for optimal water resistance and durability. Each coat should be allowed to dry completely (about 24 hours) before applying the next. Additionally, ensuring the surface is clean and dry before application will enhance adhesion and effectiveness. It’s also prudent to inspect the boat regularly and apply additional coats as necessary for maintenance.
Making a thickener with flour and butter, commonly known as a roux, is a fundamental technique in cooking, used to thicken sauces, soups, and gravies. To create a roux, start by melting butter in a pan over medium heat. Once melted, add an equal amount of flour to the pan. Stir the mixture continuously with a whisk or spoon to ensure it combines smoothly, preventing any lumps from forming. The mixture should be cooked for a few minutes until it develops a pale golden color; this cooking time helps eliminate the raw flour taste. The ratio of flour to butter can be adjusted depending on the desired thickness of the final sauce, with equal parts by weight being a common starting point. Once your roux is ready, gradually whisk in your liquid (such as milk, broth, or stock) and continue to cook until the sauce reaches your preferred consistency. Remember, the sauce will thicken further upon cooling, so factor this in when deciding when to remove it from heat.
Yes, Tylenol, specifically some formulations such as Tylenol Extra Strength, can contain polyethylene glycol. Polyethylene glycol (PEG) is used in pharmaceuticals as a solvent, plasticizer, surfactant, or ointment and suppository base. Its inclusion in medications is generally for improving consistency and absorption. However, concerns about allergies and sensitivities to PEG have been raised, though such reactions are rare. If you have a known sensitivity or allergy to PEG, it's crucial to read medication labels or consult with a healthcare provider before taking any new medication, including over-the-counter products like Tylenol.
