I was determined to spend some extra time this spring renewing the gelcoat on my Cal. I was not sure which products on the market I should use, particularly since I was pretty sure I wanted to use a multi-step process. This kit turned out to be perfect. A matched set of products in the right proportions was included. The grinder included is not the best quality, but it was more than up to the task of polishing a boat. Lots of people stopped to ask what I was using to get such a good finish. The results were great and I'll use the same components, and the same grinder, again next year.
I used this product to work on a mold for a light vehicle. I purchased the kit because it made shopping easier but discovered that I wanted more of some of the products and less of others. Next time round I used the list of included products to build my own 'kit'.
