Re: Epoxy over Polyester resin?
Please let me make a suggestion to you, other than to do all this work in a well ventelated area. If you don't already have one go buy yourself a good quality, but not overly expensive, small (4 1/4") angle grinder. It will become your most valuable tool for this project and a good one shouldn't cost you more than about $80 at the most if you look around. Pick up a hard rubber backing disk for it (it will probably come with metal grinding wheels, but you can use other wheels) and the grinding disks that look like coarse sand paper. Get yourself some 36, 50, and 80 grit disks for it, any Home Depot or Lowe's will carry them for a couple of bucks.<br /><br />Prep your area with the 36 grit wheel, wash it, and just befor you lay up glass wipe it down with clean rags and acetone (remember that ventilation). Your bonds will be stonger than a polyester to polyester bond would have been. Also, and this is an important one, anytime you apply epoxy over top of epoxy if it has been over 24 hours between layers you need to first wash with soap and water and then grind the top of the old stuff before you put on a new. If you do not do that you will not get a good bond because of the amine blush that will form on the top of the earlier layer. Washing and grinding removes the blush and will give you a good surface for a mechanical bond.<br /><br />Thom
