Very satisfied with the Product, does a great job in restoring a dull aged finish to like new condition.

Expensive but worth it


I used the product to bring back to life the faded fiberglass on a Boston Whaler 17' Montauk. It's important to use enough compound so that the polishing process does not miss any spots. It's best to squeeze the compound onto the wool buffing wheel, then smearing it around the hull to avoid splattering. Again, don't skimp on the compound. Yes, it's expensive but it's worth it.




Great product


Quick and easy, gave results much better than other products. Cut time in half to polish 40' boat that was in very poor condition.

This compound is no Joke!


This compound works 3 times better the the Buff Magic I had been using. Not knocking the Buff Magic, but for the amount of oxidation my boat had this stuff worked GREAT! I compounded a 2000 Century 2100DC that appeared to have never been buffed or waxed, and 3M Imperial Compound brought back to a mirror finish.

Does exactly what it claims to do


This compound saves me from having to go around the boat and polish again, it does 2 jobs in one, I used to do compounding, then finesse it swirl mark remover, this imperial compounding does it all in one time. It made the hull look new again, and i only had to go around the boat twice not 3 times, a 34' sail boat gets very big when you have to do it 3 times. I used the entire container to do the boat.

Looks like a new hull!!


Must use foam pad at 2000rpm and do a 2'-3' square area at a time ( credit given to Sail magazine 4/08 by Geoffrey and Pam Shattuck. For perfect results follow their instructions.

I am polishing a 16 year old black hull that has faded. First tried to use this product with a Porter Cable random orbital buffer using a foam pad and the results were so so. Then used a 3M wool buffing pad and a Dewalt DW849 buffer and the results are amazing. It is truly a mirror finish.
