AeroShell & Silmid Celebrate 40 Years in Partnership

2022 marks an incredibly special anniversary for Silmid; it's our 40th year partnering with AeroShell. Our partnership began in 1982 when we had the opportunity to start repacking AeroShell Fluid 3, which is one of many products we still repack today. Fast forward to 2022 and we offer the full AeroShell product portfolio, supplying customers in over 120 countries via our best-in-class Ecommerce platform. 

Over four decades the world has changed a lot but with AeroShell’s diverse product portfolio and our commitment to first class service our partnership has not only endured but thrived. 

Throughout 2022 Silmid and AeroShell will mark the anniversary with awards to longstanding customers, giveaways and more. 

Stay tuned for more over the coming months...
