APPLICATION: Apply TR-108 with sponge applicator in thin even circular motion to the mold or pattern surface working in small 3’ x 3’ overlapping sections. Polish wipe applied wax while still slightly soft or wet to gloss finish frequently rotating cloth (do not allow wax to set). For new or reconditioned molds apply a minimum of 6 coats of paste wax, waiting approx. 30-60 minutes between applications for the wax to harden after the polish wipe. Best results obtained if after application mold is allowed to stand overnight and a subsequent final coat of wax release applied following day prior to gel coating. Follow with a coat of wax for the first 2-3 parts released. Then determine how many parts can be effectively produced before re-waxing is required. This will vary depending on molding condition, configuration, resin, mold cycles, effective cure of production gel coat and other factors.


Clean all brushes, rollers and fibreglass tools with Acetone.


Always wear gloves and dust masks and avoid breathing vapours of resin or dust residue.
