Maintenance Tips

I

Seal­ing an alu­minum boat not only helps keep leaks at bay but also extends its lifes­pan. Here’s a sim­ple main­te­nance guide that’s easy to remem­ber:

• Prep and Clean: Start with a sparkling clean boat. Dirt or grease can hin­der the sealant’s adhe­sion. Scrub it down with a clean­er suit­able for alu­minum.
• Prime Time: Apply a primer designed for alu­minum. It preps the sur­face and increas­es the sealer’s effec­tive­ness.
• Seal the Deal: Now, grab your alu­minum boat seal­er and get down to busi­ness. Apply it even­ly, pay­ing spe­cial atten­tion to riv­ets and seams. Let it cure as per the manufacturer’s guide­lines.
• Inspect Reg­u­lar­ly: Post-seal­ing, reg­u­lar inspec­tions are vital. Look for signs of wear or dam­age that might need a touch-up.

Well-sealed boat is a hap­py boat. So get that seal­er out and give your alu­minum bud­dy the love it deserves!
