Dear Mr. Banks: This is in reply to your letter dated January 29, 1975, asking whethe a product which you use to repair damaged windshields is prohibited by Federal law or regulation. Your letter was forwarded to our office by the NHTSA Regional Administrator in Fort Worth. You describe the repair process which you use as one in which the air in a damage spot or crack in the windshield is displaced by the product in a liquid form. As this product hardens it bonds itself to the glass, making the damaged area stronger than the other areas of the glass.; There are no Federal laws or regulations which prohibit the use of suc a material or process in the repair of windshields which have previously been installed in vehicles and damaged in use. Using such a material or process in a *new* (but damaged) windshield (such as in shipment) could cause the windshield to fail to meet the performance requirements of Motor Vehicle Safety Standard No. 205 (49 CFR S 571.205) and we would therefore discourage its use in new windshields.; We are pleased to be of assistance. Yours truly, Richard B. Dyson, Assistant Chief Counsel
