5 Tips on how to use Brushable Gelcoat

Brushable gel

Brushable Gelcoat is a specially formulated product that is made to be applied like paint and eliminate the need for spray equipment. It has excellent leveling, Water/Osmosis resistance, UV light Stability, great Gloss Retention and a fantastic long-term durability. It comes in many different colors and can be bought online or in our stores! So, let’s talk about some tips on how to get the most out of the Brushable Gelcoat.

  1. Don’t add Patch Booster or Sanding Aid! You heard that right, you don’t need to add sanding aid to Brushable gelcoat to have it dry tack free! The self-leveling technology added doesn’t require any additional products or additives.
  2. Proper gelcoat application requires you apply your coats about 15-20 mils thick,

    using a mil gauge.

  3. Allow the gelcoat to cure overnight and then lightly sand it and buff it for an outstanding shine!
  4. Use Acetone for your cleanup. Just like other Polyester-based products, Acetone is the best cleanup material!
  5. The most important step: Adding the proper amount of Catalyst. We recommend 1.5%-2% Catalyst ratio. After adding the catalyst, you will want to mix for two minutes, preferably with a mechanical agitator (drill mixer). For your reference, here is the catalyst chart so you know exactly how much catalyst you need.

BONUS TIP: In the hot Florida weather, working time is tough for any gelcoat. So our FGCI Pro Tip is to chill the gelcoat down to 70 degrees before mixing. This way you can get a bit longer working time.

Tips & Tricks on OEM Super Poly-Fill (w/ video)

polyfill2One of our top products is a filling/fairing putty called OEM Super Poly-Fill. It’s now being sold through Amazon.com and Ebay.com so we wanted to take a moment and give you some tips from the pros on how to make sure your project benefits from this product.

  1. It uses MEK-P just like Polyester Resin does, so you want to refer to the catalyst chart for mixing ratios:catalyst chart small
  2. Do your surface prep! Make sure you clean the surface, remove any paint or rust and rough the surface with some sandpaper to get the best adhesion.
  3. The product working time is 12-18 minutes, IF catalyzed at 1% and if it’s the magic temperature of 77 degrees in your working area. If it’s hotter out, and we all know it will be, our pros recommend cooling the product down before use to extend the working time.
  4. If you are using it to fill holes, always fill a little high and plan for a slight amount of shrinkage. Once it dries, you can easily smooth it out with a little sandpaper.
