303 Aerospace Protectant on Gelcoat Fiberglass

Gelcoat fiberglass is polyester resin with the pigment in the resin, commonly used in boats, RV's, snowmobiles, jet ski's, etc.  Gelcoat fiberglass rapidly fades and chalks with traditional maintenance being tedious and repetitive buffing and waxing.

303 Aerospace Protectant is an alternative to buffing and waxing.  303 restores like new color and gloss to faded gelcoat fiberglass by spraying on and polishing completely dry.

A new appearance is maintained with periodic spray on/wipe off applications usually every 45-60 days of exposure.  Fiberglass shines.  Colors stay bright.

In addition,  the 303'd  surface is extremely repellent to water, soiling and staining ... staying cleaner longer and clean up is much easier when soiled.

So for gelcoat fiberglass 303 Aerospace Protectant is a superior with respect to ease of use, level of protection, appearance and repellency.

Restoring Gelcoat with 303 Aerospace Protectant

Gelcoat Fiberglass Application

Method 1).
Spray 303 on the surface liberally, rub it around with your hand or a thoroughly saturated sponge or cloth to assure the gelcoat is thoroughly wetted with 303.  After a couple of hours if any portion of the surface is dull, apply more 303 to that portion.  Let soak in for 12-24 hours.  The entire surface will look like new, but to complete the job all the unabsorbed 303 must be wiped away.  This is easily done with a clean towel and bucket of clean water.  Soak the towel in the water, wring out most of the water and wipe down the gelcoat.  If it is a large area, you will have to rinse out the towel periodically. 

Method 2).
Wash the surface to remove surface dirt & grit.  Then use a variable speed power buffer (set not to exceed 1800 rpm) with a synthetic wool pad(or equivalent).  Spray 303 on the surface, spread with the buffer on low, then increase the Rpm's & buff in until dry.  Professionals utilizing this method achieve a labor savings of at least 80% compared to standard buffing & waxing, while producing a more lustrous and beautiful, longer lasting finish.

Note:  In some cases, pre-buffing may be required.  Be sure to use a buffing compound which leaves no wax or polymer finish.

RESULTS/BENEFITS:

Once properly applied, 303 Aerospace-treated gelcoat repels dust, dirt and moisture, stays cleaner longer and cleans up easier when finally soiled. 

To prevent the reoccurrence of both UV fading and oxidation, periodically reapply 303 Aerospace Protectant (spray on/wipe dry).  This will provide continuing UV protection and keep the gelcoat surface like new.
